This is the story of a little girl whose home was among the Green Mountains of Vermont, then known as "The Wilderness," at the beginning of the American Revolution; and at the time when Ethan Allen and his brave soldiers were on guard to defend their rights. Ethan Allen was the friend of Faith, the heroine of the story, whose earnest wish to be of help is fulfilled. She journeys from her Wilderness home across Lake Champlain to Ticonderoga, and spends a winter with her aunt and cousin near Fort Ticonderoga. Here she learns a secret about the fort that is of importance later to Ethan Allen's "Green Mountain Boys."
