Following her powerful debut in The Witch’s Orchard, private investigator Annie Gore returns in Brimstone Hollow, bringing readers back to the mountains that author Archer Sullivan, a ninth generation Appalachian, knows so well.

There isn’t much that happens in the Appalachian Mountains that Private Investigator Annie Gore hasn’t seen. Before she joined the Air Force, she was born and raised in those rolling hills, and lately Annie's cases have called her away from her Louisville office and closer to the small towns of her youth than she ever anticipated. But when her newest client asks if she’s ever been to a snake-handling church, Annie knows she’s about to enter unknown territory.

Katie May has been estranged from her father—one of Appalachia’s last infamous snake handling preachers—for twenty years. But when Katie finds out he’s been fatally bitten, and a funeral was held within twenty-four hours, she questions whether someone deliberately rushed the process. Despite Annie’s doubts, she takes the case. After all, when she looks at Katie, she sees a version of herself: a girl who needs to understand her father in order to understand herself.

As she navigates the hidden hollers and dangerous secrets of this insular Eastern Kentucky town, Annie works fast, hoping to find the truth in record time for her client—and before too many memories from her own childhood surface. But it soon becomes apparent that someone wants Annie’s investigation to stop—by any means necessary.
