About This Book

What if everyone around you had missing parts, but yours was hidden deep inside? Imagine living in a city rebuilt after an epidemic, where your father’s inventions keep people moving, but your own heart ticks like a secret machine. When you discover a lost hand on the beach, could building a companion change everything—and reveal the truth about your family?

Suitable for ages 9-12, it thoughtfully addresses complex emotions and societal expectations in a speculative fiction setting.
