Brilliant mathematician Biba is intense, driven, and speaks her mind. Substitute teacher/world traveler David makes Matthew McConaughey look uptight. Only The Suitor can bring them together Biba: I have a life plan: Established career + suitable partner who ticks my boxes (let Maman help with this) = simple and secure married life. Love can’t be a variable in this equation. Watching Bexley on The Suitor, with all the drama and competition and crying over does-he-love-me-or-does-he-not proves love is a game that I refuse to play. I’ve got the numbers to show happily ever after doesn’t last. Until I start questioning everything. Because of David. David: Watching my ex-girlfriend compete for The Suitor might have been a lot more painful if I didn’t get to watch Biba watch the show. Everything about her fascinates me—the way her brain works, the hidden vulnerability, and especially the pink lipstick. I know I don’t fit into some complicated plan she has for a happy life but for the first time in her life, Biba is wrong. Love should be a part of the equation and I’m going to prove it to her. Can complete opposites Biba and David figure out the formula to happily ever after? Fraternizing with the Ex is the third book in the Suitor Science Series, a charmingly sweet, dual POV, laugh-out-loud romantic comedy that tries to solve the perfect equation for love.
