"A striking fiction debut." --Publishers Weekly, starred review
"An insightful, funny, and realistic coming-of-age story." --Kirkus

Dolores Mendoza is not thriving. She was recently diagnosed with a chronic bladder condition called interstitial cystitis. The painful disease isn't life-threatening, but it is threatening to ruin her life.

Just when things seem hopeless, Dolores meets someone poised to change her fate. Terpsichore Berkenbosch-Jones is glamorous, autistic, and homeschooled against her will by her overprotective mother. After a rocky start, the girls form a tentative partnership. Beautiful, talented Terpsichore will help Dolores win back her ex-best friend, Shae. And Dolores will convince Terpsichore's mom that her daughter has the social skills to survive public school. It seems like a foolproof plan, but Dolores isn't always a reliable narrator, and her choices may put her in danger of committing an unforgivable betrayal.
