From Publisher's Weekly:
""Fat Charlie" Nancy leads a life of comfortable workaholism in London, with a stressful agenting job he doesn't much like, and a pleasant fiancée, Rosie. When Charlie learns of the death of his estranged father in Florida, he attends the funeral and learns two facts that turn his well-ordered existence upside-down: that his father was a human form of Anansi, the African trickster god, and that he has a brother, Spider, who has inherited some of their father's godlike abilities. Spider comes to visit Charlie and gets him fired from his job, steals his fiancée, and is instrumental in having him arrested for embezzlement and suspected of murder. When Charlie resorts to magic to get rid of Spider, who's selfish and unthinking rather than evil, things begin to go very badly for just about everyone. Other characters...are expertly woven into Gaiman's rich myth, which plays off the African folk tales in which Anansi stars. But it's Gaiman's focus on Charlie and Charlie's attempts to return to normalcy that make the story so winning—along with gleeful, hurtling prose."
I've long loved Anansi stories. If you can suspend disbelief for a while, you'll be rewarded with a wonderful story. Charlie and Spider discover how intertwined their gifts are and how balanced their lives can be if they work together. It all starts with a song and it ends with a song.
