In this novel, Olympic athletes are allowed to “enhance” their bodies, to the point that they will not survive more than a few years after the competition. Unless they win, that is, in which case they join the ruling council and are “linked” to a neural interface that fixes the issue. Mildly entertaining.
The Dream Park Series – Larry Niven & Steven Barnes
- Dream Park
- The Barsoom Project
- California Vodoo Game (sometimes published as “The California Vodoo Game”)
The novels are set in a theme park named “Dream Park”. Dream Park uses holograms and other methods to create completely lifelike environments for adventures. For example, one can become a group of medieval knights on a quest, and be totally immersed in the experience. The novels are very enjoyable, with some nice twists to the tale. It is also interesting to see how role playing as a sport evolves from the first to the last book.
Scatterbrain – Larry Niven
Well, he certainly is a scatterbrain, as he readily admits in the introduction. Although I feel that Niven’s writing has been in a steady decline for the past couple of decades, his short fiction and especially his articles are always great fun. Like N-Space and Playgrounds of the Mind this is a mix of new and old short fiction, book excerpts and articles. Enjoyable reading for the Niven fan.
N-Space and Playgrounds of the Mind – Larry Niven

If you’ve never read Larry Niven, these two collections are a great place to start. They are both a mix of essays, short fiction, and excerpts from novels. If you’ve already read practically all of Niven’s work, there is not a lot of new material, but the convention essays still make the books worth the read.
Destiny’s Road – Larry Niven
On a distant colony planet, a boy grows up wondering why the original colony ship departed many generations ago, at the same time scorching a road into the distance with its fusion drive. No knows where the road leads. The planet has a shortage of potassium and an upper class distributes what turns out to be potassium in exchange for their ruling status.
The ideas underlying the story are very clever. Unfortunately the story itself is confusing and hopelessly. I could barely finish the book. Given the neat premise, I wish Niven would have written an outline and contracted some other author to write the actual book.
Note: This is set in the same universe as The Legacy of Heorot and Beowulf’s Children, but there is no connection between the stories beyond that.
Juggler of Worlds – Larry Niven & Edward M. Lerner
In this standalone sequel to Fleet of Worlds, ARM agent and professional paranoiac Sigmund Ausfaller is obsessed with the enigmatic Puppeteer race. The book follows his career from recruitment to ultimate savior. It is a long and complex tale that touches on many points and characters covered in Niven‘s Known Space stories from decades past.
Fleet of Worlds is a pretty decent book. More importantly, it really took me back to the Niven’s classic Known Space novels and short stories. Juggler of Worlds unfortunately does not live up to its prequel. The plot is razor thin. The objective seems mostly to fill in the gaps between various Beowulf Schaeffer stories. Cute for the Niven fan, but it falls wells short of what I expected.
Love the cover though.
Fleet of Worlds – Larry Niven & Edward M. Lerner
A new novel in the Known Space universe, “Fleet of Worlds” fills in some gaps in the story of the Puppeteers and the migration of their worlds (the “Fleet of Worlds”). It tells the previously unknown story of a society of humans living with the Puppeteers without knowledge of their heritage. The Puppeteers have some deep, dark secrets revealed. There are some excellent descriptions of Puppeteer society. We are also introduced to a younger Nessus, the Puppeteer featured in Ringworld.
It is a good story, and long awaited for any fan of Known Space. Unlike the third and fourth Ringworld novels, it really manages to capture the tone of the main Known Space novels. I hadn’t realized how much I missed the environment. Note, though, that you you will have a hard time following without at least having read Crashlander or Neutron Star (Crashlander reprints all the stories from Neutron Star).
A Hole in Space – Larry Niven
This outstanding short story collection mostly contains stories that are set in deep space, as opposed to his other collections where the setting tends to be planetbound. The first is the excellent “Rammer” (which formed the basis for A World Out of Time), in which a man revived from cryogenic sleep is forced to pay his debt to society by going on a centuries long mission to “seed” potential colony worlds. There is also an essay on space habitats, including Niven’s Ringworld concept.
The Patchwork Girl – Larry Niven
This novel, illustrated in the original editions, features Gil “The Arm” Hamilton, the detective protagonist of the stories in Flatlander (most of which were published earlier in “The Long Arm of Gil Hamilton). A woman is accused of murder and Gil must clear her name before she is executed and ends up in the organ banks.
The novel is rather short but a solid story from Niven at the height of his powers. If you can get hold of one of the original editions, the illustrations are have a nice retro feel.
Niven’s Laws – Larry Niven
Convergent Series – Larry Niven
This collection is a mix of Known Space stories, Draco Tavern stories and unrelated stories. There’s some great stuff in here, including the outstanding Dry Run, in which a man is doing a dry run with his dead dog in preparation for disposing of his wife’s body. Vintage Niven.
All the Myriad Ways – Larry Niven
This short story and essay collection contains some of my favorite stories of all time. For example Becalmed in Hell is about a man and his machine partner exploring Venus. It has a very clever psychological twist. Inconstant Moon, which won the Hugo in 1972, is about a couple of people inferring a great disaster on the far side of the world. Epic stuff. Man of Steel, Woman of Kleenex is a hilarious essay about the problems Superman would have mating with the hypothetical woman “LL”. It may be one of the funniest things ever written. You can read it here in its entirety.
Inferno – Larry Niven & Jerry Pournelle
Author Allen Carpentier is at a science fiction convention when he falls out of the window of his hotel room. He finds himself in Hell. Determined to grasp control of the situation and achieve redemption, he starts on a journey through a slightly modified version of Dante‘s hell, guided by a man called Benito.
The idea behind this novel is classic. A modern retelling of Dante’s Inferno! Great fun despite the subject matter.
Ringworld’s Children – Larry Niven
In the fourth Ringworld novel, Louis Wu is, as usual, conscripted to do a powerful being’s bidding. In this case it is the Protector Tunesmith.
Ringworld and The Ringworld Engineers are some of the best hard SF books ever written. On the other hand, The Ringworld Throne was an enormous disappointment, and given that I expected to dislike this offering. I was pleasantly surprised. The characters are well defined as usual with Niven, and the story, while not too complex, runs along nicely.
The days of truly epic tales from Niven seem to be over. Nowadays, he writes little idea pieces like this one, or collaborates with other authors. If you enjoyed the first two Ringworld novels, you will like this one. However, I think it would be impossible to read without having first read the other ones, and probably some of the other Known Space stories.
The Ringworld Throne – Larry Niven
Louis Wu must deal with a couple of crises on the Ringworld.
This direct sequel Ringworld and The Ringworld Engineers has none of the good qualities of the two first books. It is confusing, unfocused and adds nothing Known Space. Avoid it.
Rainbow Mars – Larry Niven
In this novel-length sequel to The Flight of the Horse, time traveler Svetz continues his adventures. Unfortunately the story is both confusing and unengaging.
The Flight of the Horse – Larry Niven
In this, hilarious short story collection, time traveller from the future Svetz has to go back in time and collect fauna from our time in order to populate the ruler’s zoo. Unfortunately, the time machine has the unexpected side effect of making him chase after mythical creatures. The horse is actually a unicorn and so on. The past is a fantasy version of the real past. Poor Svetz has to contend with quite a few mishaps with dragons and the like. A lot of fun, much of it with Svetz as the punchline.
The Flying Sorcerers – David Gerrold & Larry Niven
Shoogar is the greatest wizard his primitive village has ever known. Then a strange new wizard literally drops from the sky. Of course, they new wizard comes from a very advanced culture. Mayhem ensues.
There is a lot of humor in this book as magic meets technology. There are also many more or less good puns. I enjoyed it but it is far from a must read. The joke gets a bit old.
Limits – Larry Niven
Not Niven’s best collection, but it still contains quite a few entertaining stories. This is a mix of free-standing short stories, some written in collaboration with other authors, and some shorts in Niven’s Draco Tavern setting.
The Integral Trees and The Smoke Ring – Larry Niven

Set in the same universe as A World out of Time but only very tenously connected to that novel, these series of two should be read as a set. The novels are set in which is not really a world. A “smoke rIng” of atmosphere and biomass orbits around a neutron star, forming a huge but habitable donut-shaped space. In other words, no gravity. Humans have colonised this “smoke ring” in various ways. Enjoyable, but more for the wickedly cool setting than for the stories.
Note: These are now also published in an omnibus edition.
A Gift from Earth – Larry Niven
Set in Niven’s Known Space, more specifically on the world of Plateau, where the only habitable location is Mount Lookitthat, an area half the size of California that rises above the toxic clouds that range the planet. The crew of the initial colony ship set up an elitist society in which “crew” are first class citizens and “colonists” are lower class. This distinction is particularly noticeable when it comes to medical care. Capital punishment is used even for small offenses. Convicted criminals are harvested for their organs, thus allowing “crew” to extend their lives with transplants. Then a ship comes from Earth with some disruptive new technology.
While not one of the more flamboyant Known Space novels, it is cleverly constructed around some very intriguing ideas. Classic Niven.
A World out of Time – Larry Niven
This novel is an expansion of the short story Rammer from the collection A Hole in Space. Jaybee Corbell wakes up after having being cryogenically frozen after death Now he must repay his debt to society (being cured of his cancer and woken up cost a lot of money) by piloting an exploratory ramship to seed planets around the galaxy, a mission that will take centuries. He rebels and takes his ship on a long tour of the galaxy at relativistic speeds, ending up back on earth millions of years later. Reminded me a little of The Time Machine by H.G. Wells, except for the lack of a means for return.
While the short story that formed the basis is fantastic, this novel length expansion, while solid, falls a bit short of the mark.
The Emperor of Mars – Allen Steele
Jeff, a contract worker on Mars, is told that his parents, his fiance and his unborn child have died. He cannot return home for another eighteen months. He descends into a special form of insanity.
While he has written several good novels, Steele is at his best in the shorter forms, and this novelette is no exception. In fact it won the Hugo Award in its category in 2011. This story is both charming and interesting.
Man-Kzin Wars volumes I-XI – Created by Larry Niven


A long running anthology series with stories set during the Man-Kzin Wars in Larry Niven’s Known Space universe. Niven started this thing up because while the Wars were very significant in the history of Known Space, he himself was not adept at writing about conflict. Niven has written some of the stories but most are by other authors. The writing ranges from average to excellent. Recommended if you are a fan of Known Space.
Flatlander – Larry Niven
All the Gil “The Arm” Hamilton stories collected in one volume with a previously unpublished story. These are good SciFi murder mysteries set in the Known Space universe. It just goes to show that Niven has a devious mind. As he says himself, SciFi murder stories are tricky since the reader must know all the “rules” of the environment in order to have a shot at solving the mystery himself.
Note: Most of the stories were previously published in “The Long Arm of Gil Hamilton”.
