Ramona Lambert is a typical shy, artistic sixteen-year-old. She has a best friend whom she’s known since they were in diapers, parents who love her, a love for cosplay, and a crush on the cute boy in her class. The only problem? Her best friend moved away, her parents don't quite understand her love of cosplay, and she is pretty sure her crush has no idea she exists.

To escape her troubles, Ramona turns to cosplay and her original character, Rel, who gives her the confidence and freedom that she lacks in real life. Embracing this confidence, she decides to strike up an email conversation with her crush, Caleb Wolfe, from her cosplay account in the hopes getting to know him...and maybe win his heart. Then, as Caleb and Ramona are swept up in their emails back and forth to each other, Ramona falls even harder as he opens up about his hopes, insecurities, and his own geeky loves.

However, as Caleb starts to grow closer and closer to Rel, he also strikes up a friendship with Ramona, who knows she can't keep the truth about Rel from Caleb but isn't sure she is ready to risk losing him. With an important cosplay convention coming up and the anxiety of her double-life weighing on her, Ramona has to decide if she’ll hide behind her cosplay character forever or take the chance and let Caleb see the real her—because he might actually like her for who she is.
