I loved this book and hope there will be a book two.  This is a funny, thrilling, imaginative book.  It caught my attention immediately when Jem broke his arm and kept my attention until the very last page.  My favorite characters are Jem, who is there for everyone and willing to help others; Jesse, who is very kind-hearted and funny; and Chris, who is friendly and good at stunts with his dirt bike.  I would recommend this book to kids ages 9 and up because there is some strong language and a little violence.  Stephen V. Masse did an excellent job on this book.  I hope kids find this book as appealing as I did.
