Permafrost – Alastair Reynolds

In the not too distant future, a cascading ecological apocalypse has ended all food production. Humanity is down to stored rations, and there is no future. Mathematician Valentina Lidova is recruited to a remote research facility, where scientists are attempting practical time travel into the past, with a twist.

Mr. Reynolds’s fluid style makes the narrative of this bleak novella shine despite the grim setting and themes. The concept of inertia as history is changed, as well as the fact that characters’ memories are altered mid-paragraph due to chances, makes things potentially quite confusing for the reader, but that is not a problem here.

The Accidental Time Machine – Joe Haldeman

TheAccidentalTimeMachineIn the not-too-distant future, MIT graduate student Matt Fuller has just completed a graviton generator for his professor. He tests it and it disappears, only to reappear a second later. Further experimentation shows that the generator has, quite by accident and unexplainably, acquired the ability to jump forward in time. Matt figures out a way to go with it. There’s a catch, though. Every jump is longer than the previous one in a geometric progression, and Matt calculates that the jumps will very soon be hundreds of thousands of years long, then millions, and ever growing. Wanting to escape his personal circumstances at the time, Matt starts jumping forward.

As usual with Mr. Haldeman, the tale takes an unexpected turn somewhere down the line, in a good way. Matt travels to future societies both regressed and far progressed from our current one. This is not uniquely a touristic exploration of possible futures, however. At the core there lies a logically carved out path, interestingly ambiguous in its treatment of predestination and free will. The personal story and growth of Matt, a down-on-his-luck and rather lazy graduate student, adds a charming and personal dimension to the tale, and ensures that despite the subject matter, the novel is softer than the rock-hard science fiction of classics like The
Time Machine
or A World Out of Time.
