Query: The Best Book Ever Written

This is the best book ever written. I loved it, however, it was not so good at the end. Actually, the actually written part of the end was good, but there should definitally be a sequal to it. It definitally needs it. I'm going to write a letter to Andrew Clements and congratulate him on this wonderful book, and maybe ask him to write a sequal (which probably won't happen and if it does, it probably won't be out for 10 years- but you have to try!). I would highly suggest anyone of any age to read it!
