Golden-haired Max Monroe has it all: beauty, friends, and tons of followers. Her picture-perfect existence seems eminently enviable...except it's all fake. Max is actually Kat Sanchez, a quiet and sarcastic 17-year-old. Nothing glamorous about her existence--just bad house parties, a crap school year, and the awkwardness of dealing with best friend Hari's unrequited love. But Kat thrives as Max: doling out advice, sharing beautiful photos, networking with fans, even finding a real friend (or more?--Is Kat into girls!?) in a follower named Elena. But the closer Elena and Max get, the more Kat feels she has to keep up the façade. But when one of Kat's posts goes viral and gets back to the girl she's been stealing photos from, her entire world--real and fake--comes crashing down around her. Can she escape the web of lies she's woven without hurting the people she loves?
