Skinned, Robin Wasserman

Skinned is a young adult sci-fi by Robin Wasserman. First published in 2008, the novel has since been renamed Frozen and is the first book in the Cold Awakening trilogy. After her organic body dies in a car accident, Lia's mind is scanned and downloaded into a mechanical body with no resemblance to the original. Grappling with the concepts of personal identity and what it means to be human, Lia must decide if she wants to return to her old life or assimilate into her new one.
