It’s been 5 years since Charlotte Donovan was ditched at the altar by her ex-fiancée, and she’s doing more than okay. She has her strings ensemble, the Rosalind Quartet, and her life in New York is a dream come true. Her ensemble mate Sloane persuades Charlotte and the rest of the quartet to spend Christmas with her family in Colorado. But when Charlotte arrives, she discovers that Sloane’s sister Adele also brought a friend home—her ex, Brighton. All Brighton Fairbrook wanted was to have the holliest, jolliest Christmas—and try to forget that her band kicked her out. But instead, she’s stuck pretending like she and her ex are strangers—which proves to be difficult when Sloane and Adele’s mom signs them all up for a series of Christmas dating events. After a few days, however, things start to slip through. But it’s all in the past and nothing can melt the ice in their hearts…right?
