The De-Callen Chronicles
Two worlds exist at the same time but only one of these worlds knows this.
Karl and Tom suddenly discover that although they live on Earth, they were sent there many years ago to keep them safe from those who wished them great harm. But they have been found and their uncle must now get them back, with the sister they never knew they had, to their own world.
Adventures, good and bad, follow them as they travel back to Elemtum, meet their father and discover why they had to be sent away in the first place.
Battles take place on Elemtum and Earth, people die, others live, until the boys and their family win the day.
