Publication Date: September 16, 2025
“Dear Caitlin. Welcome to your island home. I just have one last request for you…”
Caitlin used to adore visiting Aunt Lydia at her Dune Island cottage with its quaint adjoining windmill. But even though Caitlin promised her aunt she’d return and see the island once the leaves turned golden in the fall, a life-changing encounter with a guest one season meant Caitlin fled the island and never came back.
Now Aunt Lydia is gone, leaving Caitlin both her cottage, and a mysterious request: Caitlin must return to the island for the first time in years and renovate the windmill.
Despite her troubled memories, Caitlin’s heart lifts when she strolls in the crisp autumn air before baking apple cinnamon muffins in Lydia’s kitchen. And sparks even fly between her and handsome local carpenter Shane.
But the renovations uncover an old note tucked away in the windmill, handwritten by the same girl Caitlin met here years ago. The note contains a shocking revelation. Caitlin thought she understood all the reasons she left—but what if there’s more to uncover?
Was this Aunt Lydia’s plan all along? And does Caitlin have the courage to find the truth—or will she run from Dune Island as quickly as she arrived?
An absolutely stunning page-turner that will whisk you away to a cozy cottage by the sea. Perfect for fans of Debbie Macomber, Mary Alice Munroe, and Pamela Kelly.


After two decades, an unexpected inheritance leads Caitlin Hines back to Dune Island, where she must confront a tragedy from the past.
Author Kristin Harper ties the past and present together in A Secret at Windmill Cottage. The beautiful beach setting offers both comfort and painful memories for Caitlin, who is already on edge after a breakup.
She must carry out her aunt’s last wishes to restore a windmill on the property before she can sell the cottage it is attached to. In the process, the author provides clues about the tragedy and how it impacted Caitlin.
An unexpected discovery, along with a handsome carpenter, suddenly reshapes her life. The heartwarming story also includes some dramatic events to keep a lively pace.
A Secret at Windmill Cottage illustrates how a new perspective can transform something awful into something meaningful.

Ever since she was a young girl, there were few things Kristin liked more than creative writing and spending time on Cape Cod, Massachusetts, with her family. Eventually (after a succession of jobs that bored her to tears), she found a way to combine those two passions by becoming a women’s fiction author whose stories occur in oceanside settings. While Kristin doesn’t live on the Cape year-round, she escapes to the beach whenever she can.
