One afternoon in 1839, Emily Lowry's husband vanishes from Wreckers' Cay, an isolated island off the coast of Key West where he tends to the lighthouse. As days stretch into months, Emily has no choice but take charge of Wrecker's Cay and her husband's duties tending the light to support her three children--and a fourth on the way. Unexpected help arrives when a runaway slave named Andrew washes up on their beach. At first, Emily is intensely wary of this strange, charming man, whose very presence there is highly illegal. But Andrew proves himself an enormous help and soon wins the hearts of the Lowry family. And--far from the outside world and society's rules--his place in Emily's life, as steadfast now as the light, will forever change their futures. When Emily's family is ripped apart once again, she faces untold hardships that test her love and determination and show how the passionate love of a defiant, determined woman can overcome any obstacle.
