Christmas By the Lighthouse by Rebecca Boxall

Happy-go-lucky journalist Summer has always managed to focus on the silver lining. But nothing in her life has prepared her for her husband Seth’s recent revelation: he wants a six-month break from their marriage.
Determined to stay positive, Summer decamps to Jersey to spend six months by the sea, where every passing week makes Seth more of a distant memory. Then she meets sweet, charming Jude, whose life seems to be on permanent hold even before he receives devastating news of his own. To both of them, their chance encounter feels like fate, and with Summer’s encouragement Jude embarks on a bucket list of experiences that seem to bond them for life.
When they’re together, the world is alive with possibilities, but as Christmas approaches, their time is running out in more ways than one. Will they return to the lives they left behind – or take a chance on an unknown future?
