The most memorable book I have ever read is called When You Reach Me. Its about this girl in middle school who is having the wackiest time. There is a crazy man on her street that they sometimes call kicker because he will walk around his little area and kick wildly into the air. It talk about time travel and how complex it is and it is included in the book. The main character works for a sandwich place where she, and her friends, make sandwiches for people and help out the busy own to make a few bucks. I would recommend this book if you like mystery, foreshadowing, and romance. Otherwise this book is probably not for you.
