Alice doesn't like noise, smells or strangers. She does like rules. Lots of rules.
Nobody at her new school knows she is autistic, and soon Alice finds herself in trouble because the rules here are different. When she meets Megan in detention, she doesn't know what to make of her. Megan doesn't smell, she's not terribly noisy, and she's not exactly a stranger. But is she a friend? Megan seems fearless to Alice; but also angry or maybe sad. Alice isn't sure which. When Megan decides to run away, Alice decides that Megan is her friend and that she needs to help her, no matter how many rules she has to break or how bad it makes her feel.
