Highland Beauty by Em Taylor

Everyone knows about Sadie MacNeil’s secret apart from her ex-boyfriend, Calum. It was her secret that drove them apart. Having decided that the single life was the best thing for her, Sadie has returned to Kilrigh to begin again. She doesn’t bank on Calum following her up to the small Hebridean island.
Try as she may, Sadie can’t convince either Calum or herself that she’s over him. She begins to find ways to continue their relationship while keeping her secret—ways that require her to be inventive in the bedroom. But will the consequences of an irresponsible night on the beach be the thing that pulls them together or destroys their relationship forever?
