Mary Underwater

Inspired by Joan of Arc, a girl builds and pilots a submarine to prove just what girls can do in this masterful middle-grade debut
Mary Murphy feels like she's drowning. Her violent father is home from prison, and the social worker is suspicious of her new bruises. An aunt she's never met keeps calling. And if she can't get a good grade on her science project, she'll fail her favorite class.
But Mary doesn't want to be a victim anymore. She has a plan: build a real submarine, like the model she's been making with Kip Dwyer, the secretly sweet class clown. Gaining courage from her heroine, Joan of Arc, Mary vows to pilot a sub across the Chesapeake Bay, risking her life in a modern crusade to save herself.
Mary Underwater is an empowering tale of persistence, heroism, and hope from a luminous new voice in middle-grade fiction.
