Unknown assassin

They needed the perfect assassin.
Boy Nobody is the perennial new kid in school, the one few notice and nobody thinks much about. He shows up in a new high school in a new town under a new name, makes a few friends, and doesn't stay long. Just long enough for someone in his new friend's family to die — of "natural causes." Mission accomplished, Boy Nobody disappears, moving on to the next target.
But when he's assigned to the mayor...

After breaking free of The Program, Boy Nobody is on a mission of his own to reclaim his life and rescue his friend Howard from the secret organization that has turned him and other orphaned children into trained assassins--but he has no idea who, if anyone, he can trust, or what the consequences will be if he succeeds in bringing down The Program.
