The Nightmare Room Thrillogy #3: No Survivors

Twelve ultra-smart, ultra-competitive kids have been selected to take part in a survival competition called Life Games.
Not only will they have to overcome the dangers of life on a tropical island, they'll also have to face the evil presence that lives there…waiting for its next victim. No Survivors
April must return to the island where the games began. But now the evil is ready to play the final round. And this time, there is just one rule-win, or die!Don't tell anyone the surprise ending to The Nightmare Room Thrillogy!
