I read the original Odd Thomas in 2012. Really enjoyed it.
It took me 8 years to get around to the 2nd book in the series Forever Odd.

Odd Thomas is a twenty-year-old short-order cook.
Odd is silently approached by the ghost of a young girl brutally raped and murdered, and through his unique ability to understand the dead, is psychically led to her killer, a former schoolmate named Harlo Landerson.
Koontz discloses how Odd was named and begins, layer by layer, to show how Odd’s dysfunctional upbringing has shaped his life, and as those details are uncovered, his supernatural abilities begin to make more sense.
The ghost of Elvis hangs around Odd’s apartment, for example.
“I see dead people. But then, by God, I do something about it.” – Odd Thomas pg. 32
Though the book is simplistic and silly in some ways, I really enjoyed it.
Some of the characters are interesting.
Little Ozzie, for example, a philosopher and obese gourmet cook.
Chief Wyatt Porter is good. I do like the love interest, Stormy Llewellyn.
An Odd Thomas film was released in 2013. Mostly based on the original book
