Sat 2 Success Literature
This has a decent coverage of the basics of most of what you need to know for the test, but its sample tests are horrible. Obviously, the SAT II Literature test is not a difficult level of analysis and thus its answers should be easy to explain and very concrete.
Compare this books questions to those on collegeboard and the difference is apparent; this book fails to adequately justify its answers, often dismissing the answer similar to the correct answer as being "less accurate" rather than indicating evidence from the text.
