As a third-year PhD candidate, Olive Smith doesn't believe in lasting romantic relationships—but her best friend does, and that's what got her into this situation. Convincing Anh that Olive is dating and well on her way to a happily ever after was always going to take more than hand-wavy Jedi mind tricks: Scientists require proof. So, like any self-respecting biologist, Olive panics and kisses the first man she sees.

The many lives of theoretical physicist Elsie Hannaway have finally caught up with her. By day, she’s an adjunct professor, toiling away at grading labs and teaching thermodynamics in the hopes of landing tenure. By other day, Elsie makes up for her non-existent paycheck by offering her services as a fake girlfriend, tapping into her expertly honed people-pleasing skills to embody whichever version of herself the client needs. Honestly, it’s a pretty sweet gig—until her carefully constructed Elsie-verse comes crashing down.

« Je te hais depuis le jour où j’ai entendu ton nom pour la première fois. Je te hais depuis que j’ai lu dans le Scientific American ce que tu avais fait. Je te hais depuis l’âge de douze ans. Je te hais plus que tu ne me hais, depuis plus longtemps et pour de meilleures raisons. Jack n’a plus du tout l’air amusé. Et pour moi, c’est une première.

Viola Bowen has the chance of a lifetime: to design a video game based on her all-time favorite book series. The only problem? Her co-lead is Jesse F-ing Andrews, a.k.a. her arch-nemesis. Jesse has made it abundantly clear over the years that he wants nothing to do with her–and Viola has no idea why. When their bosses insist a wintery retreat is the perfect team-building exercise, Viola can’t think of anything worse. Being freezing cold in a remote mountain lodge knowing Jesse is right next door? No, thank you.

Like an avenging, purple-haired Jedi bringing balance to the mansplained universe, Bee Königswasser lives by a simple code: What would Marie Curie do? If NASA offered her the lead on a neuroengineering project—a literal dream come true after years scraping by on the crumbs of academia—Marie would accept without hesitation. Duh. But the mother of modern physics never had to co-lead with Levi Ward.

Mallory Greenleaf is done with chess. Every move counts nowadays; after the sport led to the destruction of her family four years earlier, Mallory’s focus is on her mom, her sisters, and the dead-end job that keeps the lights on. That is, until she begrudgingly agrees to play in one last charity tournament and inadvertently wipes the board with notorious “Kingkiller” Nolan Sawyer: current world champion and reigning Bad Boy of chess.

Scarlett Vandermeer is swimming upstream. A Junior at Stanford and a student-athlete who specializes in platform diving, Scarlett prefers to keep her head down, concentrating on getting into med school and on recovering from the injury.
