It happens every year. A select few disappear, never to return.

From The Falkland Islands to the Himalayas, Puerto Rico to England - people are vanishing without trace or explanation. A young man who's lost everything stumbles across an ancient secret.

Can he unlock the mystery? Will he find those who need him?

...can he escape the Unknown?
