Open Minds by Susan Kaye Quinn
When everyone reads minds, a secret is a dangerous thing to keep.
Sixteen-year-old Kira Moore is a zero, someone who can't read thoughts or be read by others. Zeros are outcasts who can't be trusted, leaving her no chance with Raf, a regular mindreader and the best friend she secretly loves. When she accidentally controls Raf's mind and nearly kills him, Kira tries to hide her frightening new ability from her family and an increasingly suspicious Raf. But lies tangle around her, and she's dragged deep into a hidden underworld of mindjackers, where having to mind control everyone she loves is just the beginning of the deadly choices before her.
