If We Were Villains by M.L. Rio

Enter the Players. There were seven of us then, seven bright young things with wide precious futures ahead of us. Until that year, we saw no farther than the books in front of our faces.

On the day Oliver Marks is released from jail, the man who put him there is waiting at the door. Detective Colborne wants to know the truth, and after ten years, Oliver is finally ready to tell it.
