A Grown-Up Kind of Pretty book by Joshilyn Jackson

Every fifteen years, trouble comes after the three Slocumb women. When the headstrong Mosey Slocumb turn fifteen, a long-hiddengrave is unearthed in their backyard, and Mosey is determined to investigate why. The unlikely matriarch, forty-five-year-old Ginny, doesn't know the truth — she only knows she must do everything in her power to keep it hidden. Between them is Liza, silenced by a stroke, haunted by the choices she made as a teenager, with the answers trapped inside her. To survive Liza's secrets and Mosey's insistent adventures, Ginny must learn to trust the love that braids the strands of their past — and stop at nothing to defend their future.
