Jaxson is the only child of a single mom, but he's never been short on family. His best friend Logan, who has five sisters, claims Jax as a "brother." Jaxson enjoys the chaos of Logan's home, but he also loves the calm of his own. Between hanging with Logan, going to the movies with his first girlfriend, Samantha, and being the star trumpet player in the school orchestra, eighth grade is sure is looking up for Jaxson! But then Liv, the new girl at school, joins the band and becomes Jax's trumpet duet partner. Liv understands Jax's love of music better than anyone else, and the more time they spend together rehearsing, the more he finds they have in common. Soon, they learn that they share something that will change their world--something that will make them rethink what it means to be "family".
