Anansi Boys, Neil Gaiman

Everything changes for Fat Charlie Nancy, the South London boy so called by his father, the day his dad drops dead while doing karaoke. Charlie didn't know his estranged father was a god - Anansi the trickster, master of mischief and social disorder. He never knew he had a brother either. Now brother Spider is on his doorstep, about to make life more interesting . . . and a lot more dangerous. It's a meeting that will take Fat Charlie from his London home to Florida, the Caribbean, and the very beginning of the world itself. Or the end of the world, depending on which way you're looking.
