By now a well-established presence, the Bobs tackle issues large and small. The human race has all but annihilated itself in Sol system, and the Bobs must help. At the same time, the looming threat of the powerful others must be prepared for. The group continues to grow and diversify, in interesting ways.
The Others are the large, looming threat, but the story really shines in Original Bob’s interaction with the stone age Deltans. Mr. Taylor has hit his stride with the story, as each of the short chapters brings interesting developments. Interactions with humans, which some of the new Bobs have started calling ephemerals, bring challenges and solid exploration of themes. Is immortality something to wish for, or does it just involve “spending immortality doing chores”, to quote one character?
