The best LSAT book I found was "The Powerscore LSAT Logic Games Bible." I used it to study and only missed four questions on the game section.
I believe it only covers the AR section only. (The "games")
I did a couple of tests out of one of the 10 REAL LSATS book (or 10 More, I don't know), but the one that was REALLY helpful to me was Kaplan's LSAT 180. It is drilling on the toughest versions of all the types of LSAT questions - these things are really hard! You'd maybe expect 1 or 2 this hard per section, maybe only 7 or 8 on the whole test - and this book has dozens of them. I highly recommend it!
