Sometimes digging deep frees you to bloom. Sadie Tremont's will to survive is killing her. Almost 18, she's battled one mysterious illness after another. Tara-Lynn, her mom, insists she's the only one with the ultimate cure. Sadie can't depend on her dad to help when his only interest is underground caving. Her grandmother too easily counts on God to help, but Sadie has stopped waiting for miracles. Callie, a café owner and new friend, might help but can she be trusted? Then there's Sky, Sadie's new boyfriend who offers a sliver of joy, peace, and self-respect. When he schemes that the only way for Sadie to be happy is to escape with him from her native West Virginia hills by killing Tara-Lynn, she's trapped. She can't partner with Sky to hurt the mom who has hurt her for years . . . or can she? When tragedy strikes and threatens Sadie's dad's life and the shaky ground the Tremont family stands on, will they pull together or give in to the weakened earth beneath their feet?
