PRECIPICE is a book I picked up immediately after finishing OPEN SECRETS because I was fascinated by the idea of T'Prynn on the run and Diego Reyes having been captured by the Klingons. This book manages to resolve both of those plotlines but I was really much more interested in the story about Cervantes Quinn's guerilla war against the Klingons on a post-apocalyptic world. I really liked the revelation of his surprisingly dark and troubled past as well. It turns out mercenaries exist in the Federation. Who knew?
David Mack manages to insert some social commentary on the dangers of man-made climate change while also doing an Indiana Jones-style search for a Shedai relic. Chancellor Gorkon makes an appearance and that is a welcome expansion on a character I very much enjoyed. He's not a particularly nice man, threatening to murder Diego's girlfriend at one point, but he's after peace and that makes him "our" friend.
I kind of like the homages to the PRIVATE LITTLE WAR but I was a bit confused by the fact that Gorkon is so concerned about making a peace treaty now since the Organians have effectively enforced one already. There's time enough to let the ink dry on that because there's no way to actually wage war at present (which actually makes me wonder when the Organians backed off before The Undiscovered Country). If not, Chang's planned invasion of the Federation would have just been embarrassing.
Pennington and T'Prynn's bonding was an interesting part of the novel. It's interesting how Pennington really is kind of a disgusting pig and that attitude lasts until the 23rd century rather than being something that is evolved past. His wife was probably right to divorce him and that's kind of sad but fits the more "realistic" element of Vanguard's humans. Kudos, also, for T'Prynn suffering some real consequences. I've felt that heroes get off with slaps on the wrist in Star Trek way too often as, honestly, everyone but Wesley should have been expelled and probably him too in The First Duty.
I was impressed with the tie-in to the more interesting concepts of THE FINAL FRONTIER. Unlike virtually every other Star Trek fan, I actually enjoyed the concepts of that movie. I think Sybok is a fascinating character who should have at least a book or two mentioned about him. He doesn't make an appearance but Nimbus III does. I love Nimbus III as the whole idea of "Fallout planet" is something that I really enjoyed in Star Trek Online. Seeing how it gets created in this book is a lot more exciting than I think some people would have felt.
All in all, a solid piece of entertainment if not quite as good as REAP THE WHIRLWIND. 4/5
