Not in my Book by Katie Holt

Rosie writes romance novels and listens to Taylor Swift on loop. Aiden is a literary fiction writer who doesn't believe in happy endings. They're about to write a book together—what could go wrong?

The Hating Game meets Beach Read in this sexy and hilarious enemies-to-lovers romance from a debut Peruvian-Tennessean voice.

Rosie, an idealistic and passionate Peruvian American, leaves her Tennessee hometown to pursue her dream of making it in New York as a writer. But her plan is derailed when she ends up in class with her archnemesis and ex-crush, Aiden Huntington—an obnoxious, surly, and gorgeous literary fiction writer who doesn’t have much patience for the romance genre or for Rosie.

Rosie and Aiden regularly go to verbal battle in workshop until their professor reaches her breaking point. She allows them to stay in her class on one condition: they must cowrite a novel that blends their genres. 

The reluctant writing duo can’t help but put pieces of themselves into their accidentally steamy novel, and their manuscript-in-progress provides an outlet for them to confess their feelings—and explore their attraction toward each other.

When Rosie and Aiden find themselves competing against each other for a potentially career-changing opportunity, the flames of old rivalry reignite, and their once-in-a-lifetime love story is once again at risk of being shelved—unless they can find a way to end the book on their own terms.
