Our group read several of Tim Dorsey's books with the Serge and Coleman characters. We got a kick out of Serge's love of history and his intelligence. Coleman is such a loser, he makes everyone feel better about themselves. Ha!
The books we discussed and compared were:

Atomic Lobster
Hurricane Punch
Torpedo Juice

If you like to learn about Florida, there is a lot of background info shared through Serge's (verbal)thought processes.
