Ben Forta, Raymond Camden and Charlie Arehart have released the first volume of the WACK for ColdFusion 9. According to Ben Forta's blog, they waited to release the book until ColdFusion Builder was released.

I do not do much ColdFusion programming anymore, but these books are the defacto standard books for ColdFusion programming. Sometimes referred to as the "Forta" books, they are a must have if you use ColdFusion.
