The Entropy Effect by Vonda N. McIntyre

3.0

The Enterprise is called to transport a criminal, a temporal scientist, to a rehabilitation center, but complications ensue when time travel runs amok -- future versions of certain characters appear, whose actions must be prevented at all costs.

Half Trek, half Doctor Who, with plenty of time travel paradoxes, going back in time to change the future, and whatnot. Some really GOOD secondary characters are introduced, and I do hope I'll be seeing them again at some point.

I should really add an extra half star for Sulu's epic mustache on the cover...
