Swept Away by Beth O'Leary

Lexi is looking for no-strings-attached fun with a stranger. She deserves one night for herself, doesn't she? Zeke is looking for love. But for one night with a woman like Lexi, he'll break his rules. Sparks fly at the pub, one passionate kiss leads to another and they end up stumbling home to the marina together. The next morning, hungover and shaken by an amazing night together, Lexi is more than ready for Zeke to leave. There's just one small problem - the houseboat they stayed on has been swept out to sea. As their supplies start to run dangerously low, and the waves pick up, Zeke and Lexi soon realise there's much more on the line than their new relationship.
