Aiden
I met her over the summer. She was ready to lose her virginity and I was happy to help. 
Then she ghosted me, disappearing as if she never existed. Until our paths crossed and I saw her again—in the front row of my homeroom class. 
A high school student. 
A liar. 
Everything I ever wanted wrapped up in one perfect package. I should protect my career and play her pretend-we-never-met game. 
If only I could. 

Emersyn
The first day of senior year, his name was already the steady hum in every hallway.
Mr. Singleton. 
He was single all right. And more attractive than any high school History teacher had a right to be. With his perfect face and chiseled muscles, he easily rivaled a Greek god. 
The worst part? I already know him. 
We spent an unforgettable weekend together this summer. 
I didn’t intend to seduce my teacher. It just happened, somewhere among the chaos of my life. I see it every time our eyes meet—the undeniable connection that brings us closer to crossing the line every day.
What we feel is forbidden but…he wants me. 
I need him. 
We are so screwed.
