Rosie Maxwell has a plan- move to New York, get her creative writing degree from NYU, become a bestselling romance writer. But that plan is derailed when she ends up in class with her archnemesis and ex-crush, Aiden Huntington, an obnoxious, surly, unreasonably gorgeous literary fiction writer who has no patience for romance - or for Rosie.

Exhausted by Rosie and Aiden's constant verbal sparring, their professor gives them an ultimatum- leave her class, or cowrite a novel that blends their respective genres.

As Rosie and Aiden collaborate on their (accidentally steamy) novel, they try to put their differences aside. Could their manuscript-in-progress be just the outlet they need to confess their feelings - and explore their mutual attraction?

But a potentially career-changing opportunity soon reignites the flames of their old rivalry. Rosie and Aiden's 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 . . .
