Neptune's children

A day at the fabled amusement park Isles of Wonder turns deadly when a world-wide biological attack kills every adult, leaving behind only the kids to fend for themselves. Isolated from the world, unsure of what lies ahead, the young survivors assemble under the statue of King Neptune, the mythical ruler of the Isles, to form a new society. Led by the children of the park workers, they choose to remain closed off from the outside world living relatively comfortably inside the self-contained park. But when violence from the infested outside world appears to infiltrate their safe zone, one small group discovers a secret society and a hidden system of underground tunnels, and the stage is set for a war that will determine the future of everyone on the Isles.
