Ash Keller prefers to keep her heart colder than the morgue. Having sworn off love after a disastrous breakup, she's learned to thrive in her new career as a death doula. When her millionaire client, Augustus Fox, asks her to accompany him on an all-expenses paid trip to mend family ties and fulfill last wishes, she agrees.

There's just one nail in her coffin.

Nathaniel Whitford-her client's absurdly gorgeous, grumpy doctor of a grandson-is along for the trip. A man who has hated her guts since she crashed his wedding years ago. It'll be a miracle if she survives this vacation without being tossed into a volcano.

Still, Ash refuses to let Nathaniel's smug smirk and rippling pectorals take her focus away from her death doula-ing duties. She can survive two weeks in paradise with his offensively handsome face. But when falling coconuts and family drama threaten to derail the vacation, Ash and Nathaniel strike a deal: Bury their animosity and make the vacation perfect for Augustus.

Soon, a tentative bond-and mutual attraction-forms between the unlikely pair. With every tropical misadventure and steamy late-night hookup, Ash realizes there's more to Nathaniel than his barbed banter and uptight façade. Suddenly love seems more complicated than death. And as the trip comes to an end, Ash must decide whether she'll keep her heart six feet under or risk it all...for better or hearse.
