Odd Thomas by Dean Koontz

Summary: Odd is a twenty year old short order cook who sees the dead. Think 'the sixth sense' meets 'medium'. He helps the dead solve the crimes that led to their death and tries to prevent tragedy. It is very clean in the no swearing/sex part, but does have some creepy value based on the ghosts and the violent crimes in it. But the books are actually quite funny and I laughed out loud quite a few times. And you just really love Odd by the time the book is over- he is a very optimistic and innocent character who you just want to see happy. I even cried a little at the end.

New York times review:
While still sustaining the requisite level of creepiness, Mr. Koontz manages to tell a breezy, overtly inspirational story that should attract a few fans of its own … Odd Thomas walks a very thin line between the exploitation of horror and the feel-good religious optimism that transcends the darkness -
