Guilt by Association — Heather Day Gilbert

Tess Spencer hadn't planned on returning to her hometown, but when her ex-prisoner mom puts in a special request, Tess overcomes her hesitance to help her turn over a new leaf. Pearletta Vee's drug-dealing past is resurrected when the body of an overdosed teen shows up -- right next to her trailer. Tess decides to stick around and investigate, yet the evidence is stacked against Pearletta. Tess suspects a setup -- but why? Never one to back down from a challenge, Tess takes on a wayward teen, an abusive grandma, and more than one drug dealer in her quest for the truth. But it's going to take a miracle to keep her from becoming a casualty in her own personal war on drugs. Plunging into the shadowy reality of the drug epidemic in West Virginia, Guilt by Association is the third book in the award-winning Murder in the Mountains mystery series.
