Rules for Camouflage by Kirstin Cronn-Mills

Evvie Chambers is doing her best to skate through the last month of high school to graduation. The only thing standing in her way is a biology report on foxes—and her teacher, Mrs. Audrey Dearborn. The same Mrs. Dearborn who’s been a thorn in Evvie’s side for years, refusing to acknowledge or accommodate her neurodiversity. Evvie would much rather be doing her report on Aretha, the octopus she cares for when she volunteers at the Minnesota Zoo but deviating from the exact assignment is not allowed—and Mrs. Dearborn isn’t going to make following the rules easy. 
 
Evvie’s only escape from high school hell is the Lair: a safe haven for kids whose brains need some time away. But when Mrs. Dearborn refuses Evvie’s pleas to finesse the final report assignment to her strengths, and persistent bully Vandal McDaniel directs his harassment toward Lair members, Evvie finds herself more desperate than ever for stability and support.
 
When a shocking act of violence pushes the whole mess over the edge, Evvie, with the help of her friends and the others who love her, will have to figure out how to find her place in the wide world, while remaining true to herself.
