Unlovable by Rachel Kane

A professor, his student, and a trip they’ll never forget…
Taggart: The hook-up app was a last resort, to get me over the grief from my last breakup–to get over this idea that I can’t be loved. But I never would’ve downloaded it, if I’d known it was going to match me to one of my students…let alone the son of the head of my department. But that’s okay, as long as I never see Jet outside of class again, I should be fine, right?
At least, until Jet’s dad sends me on a mission to rescue a rare species, and decides Jet needs to go with me, as a character-building lesson.
Jet: Tag is everything I’m not. He’s serious, grounded, and mysteriously sad. He’s so different from the shallow boys around me, the frenemies I’ve surrounded myself with whose drama is exhausting me. But nothing can happen between us. My dad would flip out if he knew.
But once we’re in the mountains together, things change. I can’t stop pushing until I learn what makes Tag tick, but then it’s too late, the feelings are too real to hide.
How are we going to tell my dad?
