A historical treasure hunt on Pirate Island ignites local conflict and a deadly mystery for the Briar Creek library director. Lindsey is settling into her role as library director in Briar Creek, enjoying her routine and her relationship with tour boat captain Mike Sullivan. However, the arrival of a salvage company to excavate a centuries-old treasure on Pirate Island divides the town, pitting preservationists against those eager for the publicity, and soon, a murder occurs, forcing Lindsey to investigate.

The premise sets up a classic cozy mystery with a librarian protagonist, a quaint small-town setting, and a historical treasure hunt as the catalyst for a modern-day crime. The narrative is expected to balance the unfolding investigation with the charm of Briar Creek and the relationships within the community. Readers can anticipate a blend of historical intrigue and contemporary suspense, typical of Jenn McKinlay's style. The conflict between preserving local history and capitalizing on potential discoveries likely forms a significant thematic element.
