Great book to get young readers interested
Format: Hardcover
This book has been well worth its value in the first weekend. My 7 yo has read this book 3 times the same weekend it arrived. The illustrations are great and the story keeps their attention from start to finish. Great way for my 2nd grader to dive into reading more books.

My son loves this series!
Format: Hardcover
We have enjoyed each of the books in this series and pre-ordered this one and got it on release day! As always, these comic book styled readers help my son increase his reading skills while having fun! I really struggled to get my son into reading, so I am thankful to have found something that he loves to read! Every kid deserves a good book!
