Brittany Ackerman, with Sarah Cannon, Cai Emmons, and Kristen Young - The Perpetual Motion Machine

Inspired by a brother's high school science project -- a perpetual motion machine that could save the world -- The Perpetual Motion Machine is a memoir in essays that attempts to save a sibling by depicting the visceral pain that accompanies longing for some past impossibility. The collection is a science project in its study of memory, in the calculation of the moments that make up a childhood. Joining Brittany are Cai Emmons, Sarah Cannon, and Kristen Young.
