Would you ever surrender control of your mind? Eighteen-year-old Sil Sarrah is determined to die a legend. In the ten years she's been rescuing imperilled field agents for the Syntex Corporation - by commandeering their minds from afar and leading them to safety - Sil hasn't lost a single life. And she's not about to start now. She's got twelve months left on the clock before the supercomputer grafted to her brain kills her, and she's hell-bent on using that time to cement her legacy. Sil's going to be the only Mindwalker to ever pitch a perfect game-even despite the debilitating glitches she's experiencing. But when a critical mission goes south, Sil is forced to flee the very company she once called home. Desperate to prove she's no traitor, Sil infiltrates the Analog Army, an activist faction working to bring Syntex down. Her plan is to win back her employer's trust by destroying the group from within. Instead, she and the Army's reckless leader, Ryder, uncover a horrifying truth that threatens to undo all the good Sil's ever done. With her tech rapidly degrading and her new ally keeping dangerous secrets of his own, Sil must find a way to stop Syntex in order to save her friends, her reputation - and maybe even herself.
