As selected, it was ok.
*** SPOILER ALERT ***
Started out good as a mystery, then vampires got thrown in the mix.
There were just some odd things that didn't seem right or weren't consistent. Such as when two vampires decide not to kill the hero, which would have (1) solved the problem, and (2) been much easier (especially since they feed on humans anyway), but instead they throw him into the trunk of a car, drive into the desert, and bury him alive. Really?
One thing that really got me was the fact that after Jesse, our hero, finds out about vampires and his ex-girlfriend winds up becoming a vampire, she touches his hand and he shies away because of how cold her hand is, since she is after all dead. But earlier in the book when he shook hands with a vampire, there was no mention of how COLD his hand was and no one else was affected by or startled by how cold his hands were. At the end his sister doesn't react at all when taking THE vampire by the hand, yet that one time -- oh, your hand is really cold.
Also, it took days, or guess I should say nights, to change people into vampires and yet only one night to change Tracy, the ex-girlfriend, into a vampire.
