Busy flower shop manager Evita Machado can’t wait to get to Nantucket. With a bad breakup behind her, relaxing at the shore with her folks and her brothers and their families sounds like the sure cure for heartache, and their vacation destination looks like an amazing place! But when they arrive at the quaint rose-covered cottage, another group has already put down stakes: the Hatfields. Ryan Hatfield was Evita’s former crush from high school, but their business rival moms refused to let them date. Now history professor Ryan is here for a week with his parents, who won them this oceanfront rental in a society silent auction. Once it’s clear there’s been a double-booking due to a bidding mistake, Ryan’s mom digs in her heels, meaning to stay. When Evita’s mom won’t back down either, both sides tepidly agree to share the luxury accommodations by dividing the cozy space. With the boisterous Machados livening things up and the strait-laced Hatfields tamping them down, can Evita and Ryan keep the peace between the warring factions while fostering a growing chemistry between the two of them?
