Diane Carey is a wonderful "Star Trek" author, and she pulls this story off very well. Although "Ancient Blood" takes place several centuries into the future, one plot thread also gives a window into the past. The ending was slightly forced; I don't want to give too much away, but I will say that if you've watched classic detective shows ("Diagnosis Murder," "Murder, She Wrote," etc.) you've seen pretty much the same plot device previously. Still, it was a good novel, and I look forward to reading the other three books in the "Day of Honor" quadrilogy.
