Secret Intelligence

Pursued by the Ventures, the world's most dangerous and rarely known criminal organization, 14-year-old Nathan Doyle's life has changed almost instantly by numerous threats of death and the abduction of his aunt. Nathan knows very well it is the one thing he could not give up that causes all these ... but why?
He is offered help by the IIO, a secret agency that exists to control terrorism, criminals and the Ventures' activities. Seems noble, but in the world of intelligence, no one could be righteous. One tries to capture and kill Nathan, another chooses to save then exploit him.
At first it doesn't look to be the worst ... but when things get wild as his best friend is hurt by a deadly bullet, Nathan is forced to leave his old life. Whether he trusts the IIO or not, he agrees to join his first mission that will bring him to the deepest depth in the Pacific Ocean. His primary objective: to locate an illegal nuclear facility in a deep-sea research centre.
Untrained and inexperienced, the chances of survival are slim. But Nathan knows one thing for sure, he has an aunt to save. Despite everything, adventuring 3000 metres below sea level, it just takes 2 micro seconds to get killed if the glass breaks. He has to think of coming back to the surface alive.
