Rules of Rain by Leah Scheier

A dramatic new novel about the bond between a teen and her twin brother.

Rain has taken care of Ethan all of her life. Before she even knew what autism meant, she’s been her twin brother’s connection to the hostile world around him. She’s always prepared—when her father abandons them, when her mother gets sick, when Ethan is tortured by bullies from school—Rain is the reliable, stable one holding them all together. She’s both cautious carer and mad chef, preparing customized meals for her family and posting crazy recipes on her cooking blog.

Each day with Ethan is unvarying and predictable, and she’s sure that nothing will ever change—until one night when her world is turned upside down by a mistake she can’t take back. As her new romance with her long-time crush and her carefully constructed life begins to unravel, she discovers that the fragile brother whom she’s always protected has grown into a young man who no longer needs her. And now, for the first time, she finds that she needs him.
