Lord Aimsley's Return

Conceived and born enroute to Escellion, Mark and Barry Strey are the youngest colonists to ever arrive on the planet. Now they are nine years old, and officially citizens of Escellion. While on a family assignment to explore an ancient structure full of national secrets, and magic, they are swept outside of time and stranded there; untrained and unable to perform any enchantment to return to their time or any other. They find help in an unlikely place, or do they?
