Annalie and Margaret are sisters who agree on only one thing: that they have nothing in common.

Annalie is seventeen: sweet, content, and looking forward to a summer of flirting with the most popular boy in school.

Margaret is nineteen: ambitious, a warrior for social justice, and desperate to forget her ex-boyfriend in New York City.

When their family is the victim of a racial attack, Annalie tries to pretend it never happened - but Margaret wants to fight back. Suddenly their relationship - and all the ones around them - are hanging by a thread. And then a crushing secret threatens to tear them apart forever . . .
