Although maybe not the best from a literary point of view the following are on topic for this board (kind of) and are all VERY good.
Breaking Vegas - Ben Mezrich
Ugly Americans - Ben Mezrich
The Great Casino Heist - Richard Marcus
There is a 3rd Ben Mezrich book - Bringing Down The House. I've got a copy sitting on the shelf waiting for a rainy day or boring flight. Breaking Vegas is a belter, highly recomended.
PS>> If there are any Casino or Card room managers reading this.... don't worry about my reading list, I'm not planning anything
