It's a definite improvement over previous books. Characters are more interesting, Alex isn't so morose, the crime itself a tad more intriguing. Sometimes, it feels like Kellerman is playing too much with side characters, like he wonders if they're worth getting their own stories, and while I felt that here, I didn't resent it as much as I have in the past. I buy the Delaware books because I adore Alex and especially Milo. I don't really have the need to explore other possible good guys, because they're usually just not as interesting. He finally seemed to tap into some that might be worth following, however, which for me is enough to give me hope that the books themselves are returning to the exciting reads I remember.
Not one of the best in the series, but stronger than the ones previous to it. I'm still invested, and if it continues like this, will go back to buying hardcover.
