Iris moves to New York to restart her life. While at a famous autumn street fair in Little Italy, a little family-run gelateria catches her eye. Could it be the same shop that’s in an old photo of her mother’s? Iris returns the next day and meets the handsome Gio, who tells her that the shop is in danger of closing. His uncle, the sole keeper of their family’s gelato recipe, is recovering from a stroke and can no longer remember it. When Iris samples the last remaining batch, she realizes that their gelato and her gelato are one and the same. She offers her services as a chef to help them re-create the flavor and finds herself falling for Gio and his family. But when Gio’s uncle finally wakes up, all of the secrets Iris has been keeping threaten to ruin the new life --- and new love --- she’s been building all winter long.

Spending her 30th birthday alone is not what dating columnist Cleo Wilder wanted, but she plans a solo retreat to a remote Irish island in the name of re-energizing herself and adding a new perspective to her column. With his life in Boston deteriorating in ways he can’t bring himself to acknowledge, Mack Sullivan’s soul-searching has brought him to the same Irish island to explore his roots and find some clarity. Unfortunately, a mix-up with the bookings means that both have reserved the same one-room hideaway on exactly the same dates. Cleo and Mack are instantly at odds. But as the days go by, they no longer seem to mind each other’s company quite as much as they thought they would.

Lydia and Freddie. Freddie and Lydia. They’d been together for more than a decade, and Lydia thought their love was indestructible. But she was wrong.

But Lydia knows that Freddie would want her to try to live fully, happily, even without him. So, enlisting the help of his best friend, Jonah, and her sister, Elle, she takes her first tentative steps into the world, open to life --- and perhaps even love --- again. But then something inexplicable happens that gives her another chance at her old life with Freddie. A life where none of the tragic events of the past few months have happened.
