LOVE, THEORETICALLY by Ali Hazelwood

“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 favorite client, turns out to be the coldhearted 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?” Great Condition!
