Toy Soldiers (Helford #1)
On my first day of high school, they tested our abilities-they wanted to see who would outlast the others, and who would be outlasted. For hours and hours, we gave it all we had. When they came back into the room to give us our scores, we were put into two groups: the ones to be trained as infiltrative spies, and the others to be trained as assassins. I was picked to be an assassin, and later, when the members of my group turned to face the man who would mentor us, I watched as a slow, wicked smirk spread across his face. He looked at us, and he said, "Game on." This man was Shawn Masterson, and this man was a murderer.
