No book currently on the market is going to make you a Poser Pro...The only book besides the manual I have read that was worth the paper it was printed on was "Secrets of Figure Creation with Poser 5" by BLRender. My advice, read every tutorial you can find. There are tons of them if you look hard enough. Search this forum and you will find a lot of posts of great links. Also, check out all of Dr. Geep's tutorials. Up above, where the forum banner is, just underneath, you will see a link for Poser Backroom. Click that, it will take you to an area with some links. Check out the tuts section, and look at the Geep ones.
