1776. Hannah Thomas left the South to marry John, but was never quite accepted by his mother and sister. She doesn't quite fit the strict Massachusetts Puritan community, and life becomes more difficult when John is killed in one of the first battles in the war for freedom. Hannah is allowed to continue to serve as lightkeeper for the twin tower lighthouses on the lonely coastline, but it is grueling work for a woman alone. A shipwreck washes ashore a captain she thinks is a Tory, but she finds out he's working as a spy for Washington. With pressure from John's family to remarry, near-constant disapproval from the townspeople, and the appearance of her own wayward sister, Hannah isn't sure she'll ever see the light of freedom. -- adapted from publisher info.
