Ellie and the Harpmaker by Hazel Prior
When Ellie happens upon Dan and his barn full of harps, she finds her life changed. Stuck in a marriage with her controlling husband, Clive, Dan's relaxed manner and his love of nature are what Ellie's been needing in her life. Of course, it doesn't hurt that Dan is gorgeous and gives her one of his harps for her to learn to play. However, Ellie is keeping secret from Clive the fact that she is spending time with Dan and taking harp lessons because she knows Clive will be upset. As Dan's and Ellie's lives become entwined, Ellie will have to make some important choices. Give to readers who enjoyed The Rosie Project. It will be published in August.
