High Quality Content by WIKIPEDIA articles! Odd Thomas is a fictional character who first appeared in Dean Koontz`s 2003 novel of the same name, Odd Thomas. He is a twenty-year-old man who lives in the fictional desert town of Pico Mundo, California, and is able to see the spirits of the dead. He is able to make himself heard to them but they cannot speak to him, although they may make signs or mouth words. This fact complicates much of the books.
