Love Theoretically

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 supplements 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. Jack Smith, the annoyingly attractive and arrogant older brother of her favourite client, turns out to be the cold-hearted experimental physicist who ruined her mentor's career and undermined the reputation of theorists everywhere. As if fate couldn't be any crueler, this very same Jack Smith rules over the physics department at MIT, standing directly between Elsie and her dream job.

Elsie is prepared for an all-out war of scholarly sabotage, but those long, penetrating looks from Jack? The ease of not having to be anything other than her true self when she's with him? These new emotions make her question everything. Will falling into an experimentalist's orbit finally tempt her to put her most guarded theories on love into practice?
