How far would you go to protect the ones you love?Rain has taken care of Ethan all of their lives. Before she even knew what autism meant, she was her twin brother's connection to the world around him.

If only her longtime crush, Liam, would notice her too...Then one night, her life is upended by a mistake she can't undo. Suddenly Rain's new romance begins to unravel along with her carefully constructed rules. Rain isn't used to asking for help—and certainly not from Ethan. But the brother she's always protected is the only one who can help her. And letting go of the past may be the only way for Rain to hold onto her relationships that matter most.
