His Shy Girl by Landry Hill

Willow has always been muted by her nerves. It’s the reason she keeps to herself. Staying locked in her room, hidden behind her computer screen, is easier than facing the world. But next year, she’s going to be facing college.
In hopes of making the transition easier, she searches the internet for a roommate. If she gets to know someone ahead of time, it won’t be as hard to speak to them when she gets there. When she joins the incoming freshman group, she meets the perfect girl. Someone who’s interested in all the same things. And they click— instantly.
Her first true friend.
But after weeks of chatting, she learns that the perfect girl, the one she’s become close with, isn’t a girl at all. It’s one very hot, very popular, very unattainable boy.
Willow can’t speak to boys. Her nerves won’t let her.
But this boy… is bound and determined to win her heart.
