The Last Day

When 17 year old Syaoran and his little brother Chonglin jump onto a mystical train taking them away from their dystopian world to an likely safe haven, he never imagined that he would require the help of 14 year old Brenda in order to navigate this new world and to recover the stolen artifacts taken from his universe to save his almost forgotten home.
Will they make it in time to save his world... Or will he be stuck on Earth, trapped in space and time?
