American Gods
From Wikipedia:
American Gods is a Hugo and Nebula Award-winning[1] novel by Neil Gaiman. The novel is a blend of Americana, fantasy, and various strands of ancient and modern mythology, all centering on a mysterious and taciturn protagonist, Shadow. It is Gaiman’s fourth prose novel, being preceded by Good Omens (a collaboration with Terry Pratchett), Neverwhere, and Stardust. Several of the themes touched upon in the book were previously glimpsed in The Sandman graphic novels.
The Chapters are helpfully numbered 1 to 20. Enjoy!
