Genre: YA

Plot: Sisters April and Jenn haven’t been close in years. Jenn’s too busy with school, the family antique shop, and her boyfriend, and April would rather play soccer and hang out with the boy next door.

But when April notices her older sister is sad about staying home for college, she decides to do something about it. The girls set off to revive a pact they made as kids: spend an epic day exploring the greatest hits of their childhood and all that Los Angeles has to offer.

Then April learns that Jenn has been keeping a secret that could rip their family—and their feuding parents—apart. With only one day to set things right, the sisters must decide if their relationship is worth saving, or if the truth will tear them apart for good.
