I usually read books I really liked two times. I always want to read more books than to re-read old one. The Giver is my childhood classic. I completely loved the story, it was unique, and really explored the human world. This is one of my favorite books I have read more than two times, kind of the only book I've read more than two times! The next three books in the series weren't that amazing, Gathering Blue, The Messenger, and The Son. The ending of The Giver was really sad, but they are mentioned again in The Son.
