Don't Cosplay with My Heart by Cecil Castellucci

"Alls fair In love and...fandom" Overview of the book: When Edan Kupperman dresses up like her favorite character, Gargantua, she feels tall and powerful. That's important right now because her family is a mess, her best friend is gone for the summer, her crush is confusing, and Edans is feeling small and not sure which end is up. When Edans cosplaying, she can be angry, loud, and not the good girl everyone thinks she is. And when she's at conventions, she feels like she's found her own Team Tomorrow. But when her personal life starts to spiral out of control, Edan has to figure out whether she needs a side kick, or if she has the strength to be the hero of her own story.
