Junk Magic and Guitar Dreams

A guitar, a box of junk, and a pile of trouble...
Fifteen-year-old Otter is in a dark place.
Child Services wants to put him in foster care, or even a home for troubled youth.
Living on his own, he''s one bad decision away from the street. His band''s first gig is only two weeks away, but his crush on their new lead singer has him tied in knots.
Then he inherits a box of random junk from a dead grandfather he barely knew. Can his grandfather''s memories help Otter win the girl of his dreams, reconnect with his family, and keep him out of juvenile detention...maybe even become a rock star?
