I used Princeton Review's review book for Lit and got a 5, so I'd recommend it. (Hell, considering the ineffectiveness of my class, I'd say I self-studied out of
PR's book.) It's got a thorough MCQ review section as well as a really, really good Free Response review section. The FR review was fantastic, I think. They've also got two full-length practice tests.
If you have a long, long time to study, then the For Dummies book is also good - but I would use it in supplement with
PR's book. The For Dummies version is waaaaaaay too long-winded though, in my opinion, to be a good AP review book. I think it's best to use almost as a supplemental textbook throughout the course since it goes pretty in-depth into how to analyze and write and all that good stuff.
tl;dr Princeton Review is thorough, fast studying with test-taking strategies, lots of sample questions and practice passages, and a fantastic Free Response review section. Use it and see if you have any big weakness, and then use For Dummies - a really in-depth and comprehensive study book - for lots of help on how to strengthen those weaknesses.
