The Whitmore Books in Order

The Whitmore series is a newer addition to Katie Winterss island linked universe, and it leans more overtly into mystery than many of her earlier books. Set on Nantucket, it revolves around the Whitmore family and the long shadow cast by a Fourth of July fire in 1998 that destroyed their grand White Oak Lodge and seemed to end their lives together.

In The White Oak Lodge, readers meet Nina Whitmore, now a professor of anthropology at Princeton. She was ten when the Lodge burned, a night that ended with her father and brother disappearing, her mother fleeing overseas, and Nina herself being sent to live with a great aunt in Michigan. As an adult, she has built a careful, academic life and a family of her own, only to discover that her husband may have been keeping secrets about his interest in that long ago fire.

Shaken, Nina returns to Nantucket with a photograph that suggests her brother might still be alive. There she finds that the island has not forgotten the Whitmores, nor the questions left unanswered when the Lodge became a ruin. Her search for truth forces her to reconsider her marriage, her career, and the stories she has told herself to survive.

Return to Whitmore shifts the lens to Charlotte, Ninas sister, who has been living quietly on Nantucket under an assumed connection to a man who might in fact be their missing brother. When Nina shows up on her doorstep after nearly three decades apart, the fragile life Charlotte has constructed is upended. Together, they begin to piece together what actually happened the night of the fire, each discovery rearranging their understanding of their parents and of one another.

In Ocean of Secrets, another sibling, Alexander, takes center stage. Once groomed to inherit the Lodge and the family business, he fled as soon as he could and has spent his adult years miles away, trying to forget. When anonymous threats tied to the fire start arriving and his marriage falls apart, he turns to a private investigator and is pulled back toward Nantucket and the sisters he left behind.

The forthcoming Under Nantucket Skies continues to explore the fallout from that single night as the Whitmores slowly gather on the island again. Old rivalries, hidden romances, and long suppressed guilt rise to the surface while the question remains, who really lit the match that destroyed the White Oak Lodge, and why has the truth stayed buried for so long.

Through this series, Winters keeps her familiar focus on family relationships, but the pacing has an extra edge. Clues, investigators, and dangerous secrets sit alongside beach walks and shared meals. Readers who enjoy her gentler sagas yet want a central mystery to solve will likely find the Whitmore books a compelling blend of both.
