The Girl in the Cottage by the Sea by Rebecca Alexander, Laura Kirman, Emma Powell

Devastated when her wedding is called off and an injury ruins her career as a violinist, Amber escapes to her parents' holiday home on a beautiful windswept island. The charming cottage is falling apart, and Amber loses herself in the renovations. But then she meets Kai, a seriously ill young boy who loves music. Amber is determined to help him, and as she teaches him to play, she can feel herself coming back to life. Inspired, Amber's passion for music re-ignites. And she can't help but feel sparks fly between her and builder Ben, too. But will their budding romance be crushed under the judgment of the islanders, who are protective of Ben and wary of newcomer Amber? Or will the discovery of a wartime romance that blossomed in the cottage despite all the odds inspire Amber to fight for her own love story?
