The setting is the Celtic Sea of St. Ives in Cornwall where Hazel and Harry Aberdeen have moved.
The Aberdeens are preparing for the grand opening of their gallery, "H2: Art, Books, and Original Illustrations."
Hazel and Harry reflect on their accomplishments and their love for each other.
They receive a visit from their niece Midge and family friends, Fergus and Kelty.
Hazel shows concern for her appearance during her pregnancy, while Harry compliments her.
The couple runs the gallery below their flat, showcasing Harry's artwork, local art, rare books, and original illustrations.
The gallery's display includes Hazel's own memoir, "The River Child: A Memoir of Whisperwood," tied with a red silk ribbon reminiscent of the package from Hogan's.
Hazel is pregnant and secretly wishes to name her child Flora Lea Aberdeen.
Peggy Andrews, the author of the Whisperwood series and a key figure in Hazel's life, attends the opening with her fiancé, Wren.
Hazel has forgiven the past misdeeds of Imogene Wright, though she sometimes still feels anger.
Bridie and Mr. Nolan, Harry's family, announce they are staying to help with the baby's arrival.
Friends, family, and locals fill the gallery, including notable characters like Aiden Davies and Hazel's literary agent, Meg.
Harry toasts to the success of the gallery and Hazel's memoir, expressing love and gratitude.
Tim and Poppy from Hogan's make a surprise appearance during the toast.
Hazel responds to Dot's playful question about the gallery's location by referring to the magical and "liminal" qualities of St. Ives.
Hazel emphasizes the mystery and enchantment that she hopes everyone can find in their lives, much like the adventures found in rare books and illustrations sold at the gallery.
