Seven Percent of Ro Devereux - Ellen OClover

Fans of Emma Lord, Rachel Lynn Solomon, and Alex Light will love this clever, charming, and poignant debut novel with a masterful slow-burn romance at its core about a girl who must decide whether to pursue her dreams or preserve her relationships, including a budding romance with her ex-best friend, when an app she created goes viral.
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 soulmates. 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 soulmate 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. And as the app takes on a life of its own, Ro sees that it's affecting people in ways she never expected—and if she can't regain control, it might take her and everything she believes in down with it.
