Peter David is an excellent author, the best Star Trek author I've found. He is one of the few who can tell a dramatic, action-packed story without losing his sense of humor, as was done in some of the best episodes in the original Star Trek series ("Trouble With Tribbles", "A Piece of the Action", "Shore Leave") and has only rarely been seen since. I've enjoyed this series so far, and the characters in it (which is, perhaps, the most important thing in a book or a series). But there are a couple of caveats for those considering the series:
First is the one that actually bothers me a bit: I don't really care for the fact that the storyline continues from one book to the next; granted, the last two books in the series have been better about this than the first four, in that they have legitimately been complete stories in and of themselves. But I find that I prefer stand-alone stories for the most part. If you don't share this preference, you may find this a strength rather than a weakness.
Second is the caveat that does NOT bother me, but might well bother some people: while he never becomes EXTREMELY graphic, certainly never tasteless, Peter David's characters have always been a bit more obviously sexually active than we usually see in Star Trek; not that there was ever any doubt about Kirk, but even in his case, it was generally just hinted at, and that was even more true in "Next Generation". Granted, "DS9" and "Voyager" went a little farther in that direction, (remember the opening scene of "What You Leave Behind", the final episode of DS9, with Bashir and Ezre Dax naked in bed together?) but the constraints of network television still kept things a bit more restrained than David feels any inclination to. Certainly, most Star Trek novels follow the precedent set in the shows, and are much more circumscribed about showing what their characters do behind closed doors than he is. I enjoy this, but it does mean that people who do NOT enjoy this sort of thing can be unpleasantly surprised to see so much sexuality in a place that they wouldn't ordinarily expect it.
As to this book specifically, I found the story to be the best of the series so far. But really, I can't recommend it to anyone who hasn't read the previous books, so my recommendation is simply: start with Book One (House of Cards); if you like it, keep reading. If you don't, you've no need to read this one.
