Keeper of the Light Trilogy Books in Order

Also known simply as the Keeper of the Light trilogy, this series follows the O’Neill family and the community of Kiss River over more than a decade. The three books—Keeper of the Light, Kiss River and Her Mother’s Shadow—are tightly linked, each one deepening what you thought you knew about the characters and their coastal town.

The story opens in Keeper of the Light with Annie O’Neill’s shocking death on Christmas Eve. Annie is adored by nearly everyone in Kiss River, though few understand the private compromises she has made. Olivia Simon, the doctor who can’t save her, is married to Paul, the man secretly in love with Annie. Alec O’Neill, Annie’s husband, is devastated and bewildered. Much of the book explores their overlapping grief and jealousy, and the ways the old lighthouse—and an elderly keeper who knows more than he’s saying—holds the answers to Annie’s double life.

In Kiss River, the focus shifts from Annie herself to the adults her children have become. Lacey and Clay O’Neill share the light keeper’s house, trying to build steady lives in the shadow of their mother’s legend. Gina Higgins arrives from across the country with a hidden agenda: she’s determined to raise the ruined Fresnel lens from the ocean because she believes something crucial is trapped inside it. As her plan unfolds, long-guarded family and wartime secrets surface, linking Gina’s desperation to the O’Neills’ past.

Her Mother’s Shadow brings the trilogy into more intimate territory. Lacey, who grew up idolizing and then resenting Annie, is suddenly responsible for Mackenzie, the teenage daughter of her late best friend. As Lacey navigates parenting a grieving, angry girl, she uncovers new truths about Annie’s affairs, acts of kindness and failures. A parallel thread involving a nurse searching for her estranged son ties old storylines together and offers a final, surprising perspective on the family.

Taken as a whole, the Keeper of the Light trilogy is about how people mythologize their dead, how a community can both shelter and judge, and how the same small town can feel like salvation or a trap depending on where you stand. The lighthouse itself is more than a backdrop—it’s the series’ emotional anchor and the place where each major turning point seems to land.

Readers who like multi-book arcs with evolving relationships, moral gray areas and a strong sense of place will get the most out of reading the trilogy straight through from the first book to the last.
