The Circle Of Five

Long ago, there was a secret society of humans called the Circle of Five. Humans gifted with one of the four elements, fire, earth, air, and water. But one element was forgotten. Five families made up the Circle; one of the Five was lost, only four remained. No one knows where they went or if they were all wiped out by their enemies. Demons, horrible creatures damned to roam the netherworld, where they have remained for centuries, waiting in the shadows, thirsting for their chance to exact revenge on the humans who've imprisoned them.
Now they have been given their chance. Something has happeded to the Gates, the seal placed to trap the demons roaming the Netherlands has been broken. Now the creatures sealed behind the Gates are leaking out into our world.
Four unlikely children must join forces to battle the monsters appearing in their world and find a way to restore the seal and lock the monsters away once and for all. But not all humans are good. One in particular seeks to use the hidden powers within the children to free the demons and take control of the world.
Many challenges await the young heroes, great hardships will be faced and lives will be at stake as they make their journey. Hidden powers, bloodthirsty demons, evil psychopaths, and not to mention your dead ancestors ghosts come back to life. The history test next Friday is the last thing on their minds as they fight for their lives, because if they die, the whole world dies...
