A review by thestarman
The Depths of Time by Roger MacBride Allen

3.0

VERDICT: 3 stars (goodthink). Some 4-star concepts and passages, but excessive 2-star stretching out of the story. Thus 3 stars overall.

Or as one GR reviewer aptly said, "really boring but very interesting."

Two good main characters. Plot includes time-wormholes, mystery attackers, planetary terraforming going bad, long-lived characters (via technology), and a mystery or two that need solving.

Ends as things finally get more interesting. You'll have to read Boooks 2+ to find out the rest of the story (both past & present).

A borderline recommendation IF you like time paradoxes, sci-fi/mystery mashups -- AND you don't mind skimming some yawn-inducing parts, and ending on a bit of a cliffhanger.

2nd read, 3.5 years later: still 3 stars. Nice time travel method, a slog through the middle, and gets uber-preposterous towards the end.
