Good choice for a PS 7 book ?

I backed in here from the model car section...
I mostly use PS to make custom decals for model cars.
My wife however wants to do photo stuff.
While I can use the program, I'm in no position to teach her how to do things that I myself don't know how to do.
I just ordered a copy of the SAMS teach yourself PS7 in 24 hours, and I hope that will get her going.
Any ideas for a good second book?
:p

i think that anything you can learn from one of those books you can learn from the net, just google what your wife wants to do in ps then open the tutorial page open photoshop and let her go from there.
