This premise is great: Laurie doesn't believe in love at first sight. But then one snowy December day, through a foggy bus window, she locks eyes with a man on the sidewalk and she knows he's The One. But before either of them can do anything, the bus drives away. She spends the next year searching for him, but she's unsuccessful ... until her best friend shows up at a Christmas party with her new boyfriend in tow—and it's Bus Boy. Over the next ten years, we watch the characters navigate love and friendship, stew over missed opportunities, and hope for second chances.

From the publisher: "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. On Lydia’s twenty-eighth birthday, Freddie died in a car accident. So now it’s just Lydia, and all she wants is to hide indoors and sob until her eyes fall out. 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. Lydia is pulled again and again through the doorway to her past, living two lives, impossibly, at once. But there’s an emotional toll to returning to a world where Freddie, alive, still owns her heart. Because there’s someone in her new life, her real life, who wants her to stay."

From the publisher: "From the #1 New York Times bestselling author of One Day in December. Spending her thirtieth birthday alone is not what dating columnist Cleo Wilder wanted, but she plans a solo retreat―at the insistence of her boss―in the name of re-energizing herself and adding a new perspective to her column. The remote Irish island she’s booked is a far cry from London, but at least it’s a chance to hunker down in a luxury cabin and indulge in some self-care while she figures out the next steps in her love life and her career. Mack Sullivan is also looking forward to some time to himself. With his life in Boston deteriorating in ways he can’t bring himself to acknowledge, his 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 both have reserved the same one-room hideaway on exactly the same dates. Instantly at odds, Cleo and Mack don’t know how they’re going to manage until the next weekly ferry arrives. But as the days go by, they no longer seem to mind each other’s company quite as much as they thought they would."
