A good book to as2-3.0 transition

Hello everybody.

I want to talk about a book that its helping me much. Its not propaganda, I dont win anything from selling books, Im a webdesigner from Brazil.
The following title:

ActionScript 3.0 Game Programming University

is very great, at least for me, and is helping me much to understand the new way of actionscript 3.0 thinking. Im in the half of the book, reading about the paddlegame, and it is great. Hope it helps someone.
