Love Theoretically: From the bestselling author of The Love Hypothesis

About this book

Rival physicists collide in a vortex of academic feuds and fake dating shenanigans in this delightfully STEMinist romcom from the bestselling author of The Love Hypothesis - with an all-new cover, a note from Ali and never-before-seen bonus content!

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. Because 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. And he's the same Jack Smith who rules over the physics department at MIT, standing right between Elsie and her dream job.

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

*This is a reissued edition of the original Love, Theoretically with an updated cover and containing a new note from Ali herself, plus never-before-seen bonus content*
