I made it to 30% and I just can't do more. This book is just plain bad. The writing isn't terrible but it's shallow. Or, rather, the story is shallow. Lucas Davenport is...I can't find the right word. He's slime. 
No likable characters at all. No depth to the characters or the story. All police except Davenport are portrayed as having no sense at all, and... I'm just done.
