In the winter of 1856, a storm delays the lighthouse keeper's return to an island off the coast of Maine, and his daughter Abbie must keep the lights burning by herself.

The war of 1812 is raging, and from the lighthouse where their father works, Rebecca Bates and her sister Abigail can see a British ship coming. But the American troops are nowhere near! Rebecca and Abigail go the rescue--to become an American army of two--in this adventure-filled tale based on the true story of two young women who turned the tables on the mighty British army.
