When Emmy Hamilton's mother encourages her to buy the local book store, Folly's Finds, she hopes it will distract her daughter from the loss of her husband. But the seller has one condition that changes everything: Emmy must allow Lulu, the late owner's difficult elderly sister, to continue selling her bottle trees from its back yard.

For the most part Emmy ignores Lulu as she sifts through the love letters she finds in a box of used books. But the more she discovers about the letters, the more she understands Lulu. As details of a possible murder and a mysterious disappearance during WWII are revealed, the two women discover that circumstances beyond their control have brought them together, here on Folly Beach. And it is here that their war-ravaged hearts can find hope again...
