La llamada

Thousands of years ago, strange creatures, the sidhe, were banished to another dimension, the Gray Land. Now they have found a way to get revenge on the Irish: trapping teenagers and taking them into their sinister world, in a nightmare that lasts three minutes and four seconds. Most never return. Of the few who return, many are disfigured, none unscathed. To face this terrifying moment, the country's youth go to a survival school, where they receive harsh training. Nessa is fourteen years old and limps from an infection she suffered from in childhood. No one at her school expects her to survive. She's not even her parents. But Nessa is willing to do anything to prove them wrong.
