The Wanderlings: Society Of The Ancients

The Wander kids can do magic, but that has nothing to do with how they destroy the galaxy.

On a once in a lifetime trip to Earth, they find that nothing is what they were told, and and no one is quite what they seem.

They have to stop the Dragon Queen from whatever despotic shenanigans she has planned, and avoid capture by a shadowy group of time travelers.

They probably will not be successful with both.

A high fantasy adventure set in a sci-fi future with a healthy dose of dystopian time-travel.
