Welcome to Hartley-by-the-Sea in England’s beautiful Lake District, where two sisters who meet as strangers must learn not just to get along, but work together...

When Lucy Bagshaw’s life in Boston falls apart, thanks to a scathing editorial written by her famous artist mother, she impulsively accepts her half sister Juliet’s invitation to stay with her in her seaside village in northern England. Lucy is expecting quaint cottages and cream teas, but instead finds that Juliet is a distant host, the weather is wet, windy, and cold, and her new boss, Alex Kincaid, is a disapproving widower who only hired her as a favor to her sister.

Despite the invitation she grudgingly offered, Juliet is shocked at how Lucy bursts into her orderly life--and starts to mess everything up, her memories included. Lucy's version of their childhood shakes Juliet's certainties about her own, and as she faces her current challenges, both private and painful, she finds it is her sister’s irrepressible--and annoying--optimism that might be what helps her to heal.

Can these rainy day sisters find a way to seek the sunshine together?
