Audrey O'Connell has returned from Portland to her hometown of Chattertowne, Washington, a place where gossip is currency but knowing when to stay tight-lipped is priceless. Procuring a part-time job at the local newspaper to keep an eye on her impetuous sister following Vivienne's latest romantic scandal, Audrey is assigned a feature series for the upcoming festival which has her digging through the town archives in search of anything interesting. When her former boyfriend Marcus is found floating dead in the marina not long after reaching out to her in hopes of utilizing her research skills, her investigation reveals his conspiracy theories about Chattertowne and corruption within its leadership might not have been so crazy after all.

As she plumbs the depths of the town's 150-year history, she discovers that beneath the façade of this idyllic hamlet lie secrets long-submerged-including within her own family-and finds herself in the crosshairs of those who guard them.

Now with three dead bodies, an intense case of aquaphobia, and a narrow window before her deadline, Audrey looks to City Manager Holden, octogenarian historian Mildred, and her enigmatic almost-boyfriend Darren to help her discover the truth that will forever change her and Chattertowne.
