Big Brain by Cassie Mint

It’s the trip of a lifetime–ruined castles and ancient battlefields.
But I can’t stop longing for my burly professor.
A year ago, I used to see more of him. Back before the professor’s book deal and rise to TV fame, I used to visit his office hours. We’d sit and talk together; going over lecture notes and assignments.
A year ago, it felt like he was mine.
He wasn’t, obviously. Professor Munro is twice my age–and so off limits it’s not even funny. So why do I miss him so badly? Why does my chest ache when we pass in the halls? Why did I sign up for this trip, looking for any excuse to spend a few weeks near him?
And when we finally set foot in Scotland… why does it seem like the professor can’t keep away either?
