And They Had a Great Fall by Shelby Saville

For fans of Robinne Lee’s The Idea of You, a debut contemporary romance about a celebrity and a single mother who push and pull against each other as they teeter between a carrying on a secret affair and living an authentic life.
If Jake Laurent is the “human equivalent of Friday,” Kat Green is “Monday.” Nevertheless, the two shared a secret (if casual) affair during the pandemic, and now, almost exactly one year later, they’ve reunited in Copenhagen, the “city of fairy tales.” Only neither one of them is living a fairy tale.
Jake is a young actor who’s cracking under the public pressure that comes with rising celebrity. Kat is a single mother at the top of her career who believes she’s holding it all together but is barely living. Each one is a simple escape for the other—until the security Kat has worked so hard to build for her tiny family comes under threat, and Jake has to decide if he can keep Kat a secret even if it’s at the expense of his own fame.
And They Had a Great Fall is the story of two people who are going through the motions in life—until they finally look inside themselves to figure out what it takes to find a happily ever after.
