Rating: ⭐️ ⭐️ ⭐️ ⭐️ ⭐️


Ro Devereux can predict your future. Or, at least, the app she built for her senior project can.

Working with her neighbor, a retired behavioral scientist, Ro created an app called MASH, designed around the classic game Mansion Apartment Shack House, that can predict a person’s future with 93% accuracy. The app will even match users with their soul mates. Though it was only supposed to be a class project, MASH quickly takes off and gains the attention of tech investors.

Ro’s dream is to work in Silicon Valley, and she’ll do anything to prove to her new backing company—and the world—that the app works. So it’s a huge shock when the app says her soul mate is Miller, her childhood best friend with whom she had a friendship-destroying fight three years ago. Now thrust into a fake dating scenario, Ro and Miller must address the years of pain between them if either of them will have any chance of achieving their dreams.

What I liked the most

I liked the whole dynamic of the book. I had never read a book that had friends to enemies to lovers before.


Harper 360 YA was kind enough to send me a review copy in exchange for my honest opinion.

Ro Devereux is a high school senior who invented an app that can predict your future. Her life changes when her cousin promotes her high school project and makes the app blow up. A big company wants to become part of MASH and launch the partner match function. Everything is going well until Ro matches with her former best friend Miller.

Seven precent of Ro Devereux is an enemies to lover slow burn standalone. There are some technical terms in the book but nothing too complicated. Ro matching with Miller is something that’s definitely complicated. They used to be friends and have grown apart. Now they have to pretend to be in love. It’s a fun dynamic to read about. There’s awkwardness but there are also fun moments. The book also deals with serious themes. In the beginning it’s kinda brushed over it but that’s because Ro is in denial about things. They do get addressed later on in the book.

Seven percent of Ro Devereux is a book about friends growing apart and finding each other back years later, staying true to yourself but it’s also a reminder of the dangers of social media.
