Alia is an assassin. She's been selected to go on a month-long cruise ship vacation with ten other teen assassins. Five boys and five girls. But it's a game. The last person left standing, alive, wins one million dollars. So when the first teen turns up dead, Alia knows she needs to find whoever the killer is before they kill her and win the game. The ten are in trouble, especially when they can't trust anyone, and as questions start stirring about who the murderer is, they continue to strike, more and more. Alia realizes it's much more than just a game. It's survival. She must get out of the game before more of the people she cares about get killed and believes it's time to finally give herself the name "assassin" and kill, like the game told her to.
