The Things We Leave Unfinished Book by Rebecca Yarros

Twenty-eight-year-old Georgia Stanton has to start over after she gave up almost everything in a brutal divorce―the New York house, the friends, and her pride. Now back home at her late great-grandmother’s estate in Colorado, she finds herself face-to-face with Noah Harrison, the bestselling author of a million books where the cover is always people nearly kissing. He’s just as arrogant in person as in interviews, and she’ll be damned if the good-looking writer of love stories thinks he’s the one to finish her grandmother’s final novel…even if the publisher swears he’s the perfect fit.
