Always start with the positive... So, yes. I read it, lasted all the way through, and don't think of it as time lamentably and irretrievably lost.
That having been said... Is it too much to ask for books in which the Perilous Plot is advanced by means other than abject stupidity on the part of the primary characters? Particularly characters who are supposed to be so very, very smart in the first place?
It's not fair or intended that this be taken -primarily- as a slight on this particular book, it's just so damnably common a problem. This book, at least, doesn't go as far as another I won't name where the main narrating character - endlessly described as being possessed of profound (if twisted) brilliance - says no less than twelve times something like "My normally brilliant, highly functional brain just wasn't giving me the answers today." as an excuse for the bone-headed moves the author felt were needed to move the story forward.
In the Tenth Justice, a recent top-of-the-food-chain law school graduate brilliant enough to be chosen as a Supreme Court Clerk makes one bone-headed mistake. We all do this, of course, even brilliant law students. In fact, it's probably fair to say "one bone-headed mistake" has firmly taken over from "one catastrophic and unfortunate coincidence" as the primary thriller plot seed.
The main character then spends the next several hundred pages running around like a chicken with his head cut off, overreacting, getting way out of his depth, flailing about like an epileptic octopus, and inducing his friends to do the same.
Every time he effectively screams "OMG!! What am I going to do!?! What am I going to do!?!" the reader is kind of forced to think "Well, if you'd stop staring awestruck at the lofty peak of Mt. Molehill..."
Much, much (much) later in the boo we discover that he really did have -some- cause for concern, but -he- doesn't know that until well after he thinks - for no good reason we can see - that he's out of it. (Fair Disclaimer: His smarter co-clerk sees that he's still in trouble, and He's got good reason (read: character cause) to see himself as out of the woods. It's overconfident, but believable.)
At any rate... My own pet peeves aside, the character development is solid, the plot does move along, and the "Wildly Unpredictable Final Twist" doesn't come from -so- far off in in left field as to cause a brain hemorrhage. If you don't share my unreasonable demand that "brilliant" characters behave at least intelligently, you'll probably have a great ride. Even if you do share it, it's a ride worth taking.
