I've been a massive fan of (mostly) every book of the David Hunter series but this one didn't do it for me. Felt like the pacing was totally off, with nothing happening in 4/5 of the book, and then everything at once in the last 1/5. Also (and this is a point of critique I had for book 3 as well), it again felt like everything in David's favour was happening by chance rather than his competence, which is not a good thing to be going on for your main character.
