Lia Winegar and her aunt have always been thick as thieves, as close as a niece and aunt could be. Now, fresh out of high school, Lia plans to spend her last summer at home before going away to college. But as one chapter of her life closes, another begins. When she stumbles upon one of her Aunt Natalie’s old journals—along with a faded photograph of a man she’s never seen before—Lia realizes her aunt's life isn't the open book she always thought it was. Natalie isn’t the only one with a secret, though. Lia still hasn’t told her family just how far she plans to go; and while she unearths her aunt’s whirlwind story through a firsthand account, she discovers some truths of her own. As the forgotten story of one summer unfolds, how much of each woman's tale will remain undeveloped?
