Everyone else in Tally's grade seems excited for their class trip.... And she knows she is supposed to be, too. Ever since her classmates found out she is autistic, Tally has felt more comfortable being herself. But the end-of-year trip will be an entire week - her longest overnight trip ever. How will she sleep? What about all the bugs? What will her dog, Rupert, do without her at home?

Though she decides she doesn't want to miss out, bad news strikes as soon as she arrives: She isn't bunking with her friend, Aleksandra. Instead, she is rooming with her former friends and two girls from a neighboring school - who both reject Tally on day one. Tally isn't sure she'll ever make new friends. And how will she survive for so long away from home?

Told through a mix of prose.
