I ragazzi di Anansi - Anansi Boys, by Neil Gaiman (2005, UK)

Charles has a normal life, although not very successful: he lives in London, working in a company and he's going to marry his girlfriend Rosie. Then sth happens: he's got to go in Florida for his father's funeral. Since that moment, many events happen to turn upside down his life... his father turns out to be a god, Charlie's brother comes around and everything get different and troubled.
Interesting, very well written (meaningful unusual style), great.
