The Book
“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?
Who is Kristin Harper…
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.

My Review
Where can I get my travel ticket to Dune Island? From the very first page, A Secret at Windmill Cottage gave me that “happy ever after” feeling, even while weaving through moments of heartache and discovery.
Caitlin’s return to her Aunt Lydia’s cottage, complete with its charming windmill, is as much about facing the past as it is about building a future. I loved how the story captured the warmth of homecoming—baking in a familiar kitchen, breathing in the crisp autumn air, reconnecting with the land and community. The island felt so alive that I could almost hear the gulls and smell the cinnamon muffins.
The romance with Shane was sweet and tender, never rushed, and the chemistry between them made me smile throughout. At the same time, the mystery element of the windmill renovations added depth, giving the story an emotional pull that kept me turning pages. The hidden note, the shocking revelation, and the question of whether Caitlin could finally heal—all of it tied together beautifully.
Although this is book eight in the Dune Island series, it works perfectly as a stand-alone. That said, I loved it so much I have already bought the previous seven books, which are waiting on my Kindle to whisk me back to this stunning island setting.
Kristin Harper writes with such heart—her words wrap you in comfort while still tugging at your emotions. This is the kind of story that makes you believe in fresh starts, second chances, and the healing power of home.
If you’re looking for a cosy, uplifting read set against the backdrop of a picturesque island, A Secret at Windmill Cottage is a must.
