The Valentine Between Us by Megs Pritchard

Bryce thought his worst Valentine’s Day problem was breaking up with his girlfriend.
Then a party, a round of spin the bottle, and a dark closet end with him kissing his best friend and roommate, Sage—and liking it a little too much.
In the days after, everything shifts. As Valentine’s Day fades into the rest of the semester, Bryce and Sage have to decide if that kiss was a mistake… or the start of something real.
Best friends. Roommates.
One Valentine’s kiss that changes everything.
