CY

Three years ago, she saved a dying Cybertronian who became her closest friend. Now, she fights beside the Autobots and the humans who have joined their war. But one battle changes everything. Megatron leaves her broken, taking her right eye and arm—and leaving her with only moments to live. Unable to accept losing the human who has become so important to him, Optimus Prime makes an impossible choice: he orders Cybertronian technology to be fused with her dying body. She survives. But she wakes as something that has never existed before—a human with Cybertronian technology running through her veins. With a new eye, a powerful mechanical arm, and abilities she doesn't understand, she must learn how to live in a body that is no longer completely hers. Drift refuses to leave her side, the Autobots rally around her, and Optimus struggles to hide feelings that have grown far beyond friendship. Then her new Cybertronian eye begins showing a symbol no one recognizes. Megatron wants her alive. The Autobots want to protect her. And Optimus is willing to risk everything to keep her alive. Because saving her may have created something powerful enough to change the fate of both Earth and Cybertron.
