Dark Prophecy by Anthony E. Zuiker

Steve Dark is a man on a mission. He is ready to embrace his destiny, and has nothing to lose . . . Steve Dark was once a lost soul, torn between his family and his one-of-a-kind talent for hunting down serial killers especially those so-called Level 26 killers whose depravity exceeds law enforcements official scale of evil. In his reluctant pursuit of justice Dark once crossed the ultimate line, a line that might cause a lesser man to lose himself completely. Not Dark. When the world took everything from him, when it destroyed the very thing Dark once lived for, it sparked a transformation that, three years later, is only just complete. Dark is now a man on a mission. A mission unbound by authorities. A mission that, at long last, allows him to embrace his destiny. Dark is finally ready ready to take justice to the next level.

I definitely preferred the first book, but this is definitely a series I'll keep reading. This one was just a little too disconnected for me, I wasn't afraid or remotely involved in the bad guys (if that makes sense), they weren't scary and certainly didn't seem to warrant "Level 26" status. Still, I'd recommend the series as a whole and look forward to the next one :)
