Query: A must read.

I believe Tuck Everlasting is a must read book. Especially if you love fantasy and a good story. I used this book for school and read a chapter a day. The thing that always upset me, was that the chapters were so short! I wanted to find out what happened next each time. I highly suggest this book to anyone who wants to read it.
