For Cassandra Randall, there's a price to pay for being a secret atheist in a family of fundamentalists—she has nothing good to write on an online personality quiz; her best friend is drifting away; and she's failing English because she can't express her true self in a poem.

As her world fractures before her very eyes, Cass must learn to listen to her own sense of right and wrong in the face of overwhelming expectations.
