What books should I read? Or What is your favorite book?

It isn't my favorite book, but Tricks by Ellen Hopkins is heartbreaking. It's amazing, but it's really sad and deals with a lot of sensitive material so it might not be the best for you if you take issue with serious topics. Burned by Ellen Hopkins is also really good, although it deals with religion so it's a point of controversy to some people. The Tenth Circle and My Sister's Keeper are additionally very good reads, but once again they deal with controversial topics.
