Rosie Maxwell has a 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 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…

Content Warning: complicated relationship with parent
+ I had borrowed this book last year and didn’t get a chance to read it. So I borrowed it again because I needed to read a contemporary romance and this hit the spot!
+ Rosie and Aiden are writers taking a workshop class at NYU. Rosie writes romance, and Aiden writes literary fiction. They do NOT get along. They fight so much that their professor asked them to drop of out of her class or they can stay but work on a story together. This forces them to hang out together and work out their differences and it mostly works.
+ I loved the secondary characters: Rosie’s friends, her roommate and also her family. I loved the Peruvian representation since Rosie is half.
+ The romance was very rivals to lovers, almost enemies to lovers, but the tension is so strong that their attraction is as strong also, which made the spicy scenes unexpectedly spicy! Who knew Aiden had it in him 😅. Throughout the book I didn’t think he would turn out to be a dirty talker in bed! When they eventually give one another a chance, they have a fun and lovely relationship.
~ Aiden is grumpy and Rosie is sunshine but sometimes they both got on my nerves! The third act break-up actually made me so pissed off at Aiden that I didn’t want her to go back to him. But also, Rosie, really went off accusing of him of lying when really if they could just both control their tempers and talk, things wouldn’t have had to take a dramatic turn. He did do a big gesture at the end so I eventually forgave him but yeah both of them got on my nerves at times!


Final Thoughts:
I’m glad I finally read this book and I enjoyed the rivals to lovers, academia world (writer’s life), the setting of New York and how it also had some holiday scenes. Sometimes their fighting was immature or they could have had better communication but overall, I enjoyed the story.
