This is a heartbreaking story about a boy named Joseph who moves in as a foster child with Jack and his family. It is also a story of friendship and what it means to have someone’s back. The book is a quick read and as the story progresses the reader finds out about Joseph’s back story and why he ended up as a foster child searching for Jupiter.  I loved the simplicity of this book, the honest characters, and the charming setting.  If you choose to read it – have a box of Kleenex near by.  The end is surprising and had me in tears.
