A tiny-but-mighty little mouse faces down an incoming storm to protect her home. A tribute to courage and the rugged beauty of Cape Cod from Newbery Honor–winning author Lauren Wolk.

The Outermost Mouse loves her life at the tip of the beach. She has blue sky above and sand as warm and soft as her mother below.

Best of all is the house, a huge nest she has made her own. There are jam-jar posies, lanterns full of gold, and a clock that tick-tocks her to sleep at night.

But a storm is coming. When the sky goes dark and a cold wind rises, the little mouse must do everything she can to protect her home. Even though she’s small enough to fit into a teacup, the Outermost Mouse is smart, strong, and brave—and ready to face the wild waves.

Illustrator Kristen Adam brilliantly captures the snug warmth and fierce beauty of the Outermost Mouse’s shoreline world in Newbery Honor–winning author Lauren Wolk’s glorious tribute to the courage and tenacity of a tiny-but-mighty heroine.
