Sixteen-year-old Keilah Evans is completely undateable. The crush she has on Gage Fitch? Forget it. He has no idea she exists. But Keilah has something other girls at school don't: She can code. Keilah decides to solve her dating woes by anonymously creating a hook-up app. Soon, her app is in demand at every high school in the state. But instead of hooking Keilah up with Gage, the app ships her best friend with him! To make matters worse, a glitch in the app exposes student data, and now, parents, school boards, and the public are demanding the creator of the app's head on a platter. When a savvy hacker finds out Keilah is behind the app, he uses the info to blackmail her. In order to save herself and her app, Keilah must make some hard decisions, including seeking help from the last person on Earth she should trust: Ryder Coleson. With the help of some unlikely allies, Keilah will soon discover she may not be so undateable after all and when it comes to dating, there's no app required.
