For what we have lost

Ozen is a fourteen-year-old boy who lives in London with his mom. His dad died when he was seven years old.
On a sunny day, Ozen and his school friends Amein and John, see a green light blinking at the corner of a street. They follow it and arrive in front of a yellow door.
They are not the only ones to have been led to the yellow door. A boy and a girl are already there. They push the door open and the five of them enter a new world.
Amentia is a land in another dimension, where animals can talk and act like humans.
Ozen and his friends are welcome by the villagers as long expected Five Heroes. The Queen of Amentia has been imprisoned a long time ago by the horrendous King Lipanos in his Black Castle,
The Five teenagers offer to fight the evil King and to free the Queen.
From this moment on, an amazing circle of trust and friendship will bind them together and help them fight unexpected dangers.
