I took AP Chem this year, and the Princeton Review book was fantastic. Very helpful discussion of the main topics, though the reaction section was lacking in examples for me to do... That was one of the hardest parts for me, but my study buddy and I just came up with some fantastic mnemonic devices to remember all the colors and solubility rules.
Make sure you do all of the practice problems and tests, but I wouldn't do too much way before the test. The best aspect of the book was the ease of revision. It wouldn't be very good to learn from!
