I suggest reading:

-"Everything explained for the professional pilot"
http://www.amazon.com/Everything-Exp...essional+pilot

-"the turbine pilot's flight manual"
http://www.amazon.com/The-Turbine-Pi...+pilots+manual

Those two books are excellent. They explain turbine theory, advanced systems, and obscure stuff like reduced takeoff minimums. Make sure you read/brief/fly an approach!
