When she was just a tiny baby, something terrible happened to Lexi. It left her with an out-of-control body and without a voice. Now, as a precocious, superhero-obsessed 13-year-old, Lexi is counting down the final 24 hours to a risky brain surgery that might help her talk or—dare she dream it?—to walk and use her hands. As surgery grows closer, Lexi finds an urgent, relentless need to share the story of the year in her life she calls The Year of the Buttered Cat. That year, on the verge of shutting out the rest of the world, Lexi began a gutsy and solitary quest to find her "missing" body… and she learns new ways to reach out to the world to save her friendships and uncover the startling truth about what happened to her as a baby.
