Query: My sons love it

My six year old and my three year old sons absolutely love this book. My three year old has to read the alphabet listed on the inside cover. They request this often as their bedtime story. My six year old is detailed and wants to make sure he sees all the battered letters that fell out of the tree. The ending is a good lesson in not letting setbacks get you down, but to try, try again.
