Just for the Summer by Fay Keenan

When Kate Harris accepts the job of redecorating her brother Aidan’s house in the picturesque town of Willowbury, she knows it’s just a stop gap before she has to decide what to do with the rest of her life. While her three sons spend the summer holiday with their father, Kate has an opportunity to prove to herself that there is a new life, after her divorce.
Harry Sinclair is the owner of Vale Volumes book shop on Willowbury High Street. Content, if a little bored with his lot, his shop, as well as his life, could do with freshening up. When Kate offers to spruce up Vale Volumes ready for the visit of a famous author, they find they have a lot more in common than colour schemes.
But both have secrets and responsibilities, and when the trials of family life threaten their burgeoning friendship, can they overcome the experiences of their pasts? Will Somerset’s most magical town cast its spell on them? Or will Kate and Harry have to concede that their friendship really is just for the summer?
