Loni Murrow is an accomplished bird artist at the Smithsonian who loves her job. But when she receives a call from her younger brother summoning her back home to help their obstinate mother recover after an accident, Loni's neat, contained life in Washington, DC, is thrown into chaos, and she finds herself exactly where she does not want to be.

Going through her mother's things, Loni uncovers scraps and snippets of a time in her life she would prefer to forget--a childhood marked by her father Boyd's death by drowning and her mother Ruth's persistent bad mood. When Loni comes across a single, cryptic note from a stranger--"There are some things I have to tell you about Boyd's death"-- she begins a dangerous quest to discover the truth, all the while struggling to reconnect with her mother and reconcile with her brother and his wife, who seem to thwart her at every turn. To make matters worse, she meets a man in Florida whose attractive simple charm threatens everything she's worked toward.

Pulled between worlds--her professional accomplishments in Washington, and the small town of her childhood--Loni must decide whether to delve beneath the surface into murky half-truths and either avenge the past or bury it, once and for all.

The Marsh Queen explores what it means to be a daughter and how we protect the ones we love. Suzanne Feldman, author of Sisters of the Great War, writes that "fans of Delia Owens and Lauren Groff will find this a wonderful and absorbing read."
