The story begins with Odd Thomas introducing his unconventional life. He’s not seeking fame but is convinced to write a memoir by Little Ozzie. Odd assures the reader that despite the dark events he describes, it won’t be overly gloomy due to Ozzie’s insistence on keeping the tone light. He shares his peculiar experiences, like his recurring dreams of dead bowling alley employees, and describes his simple morning routine. This includes showering with peach soap given to him by Stormy Llewellyn, his soul mate and girlfriend.

Penny Kallisto, a 12-year-old girl from his neighborhood, gives Odd a shell. Instead of hearing the sea, he hears disturbing noises coming inside. As Odd waits for something to happen, Harlo Landerson, an old classmate, arrives in his car. Odd realizes Harlo murdered Penny and that Penny is a ghost and confronts him about the crime.
