How to look behind the wall

Everest was the boy in school that everyone can simply describe as "average". He could even describe himself as that. When his parents mysteriously go missing, he's left to live with his sister Abigail, who ran away ten years ago, and her husband Roland. With his distant brother-in-law, long lost sister, two love interests, and a kidnapper on the loose, will he be able to find his identity and survive the chaos? Average isn't him anymore.
