Light Riders and the Morenci Mine Murder

IT WAS ALL IN THE REFRACTION! When 13-year-old Ryn finds himself cleaning out a "hoarder's nest" that belonged to a deceased great, great aunt, he knew the summer was off to an awful start. But what he didn't know was that his "crazy Aunt Zanne" may have used prisms to find a way to travel back in time! It is only when he and his younger sister, Aeden, come across an 80-year-old picture of Ryn that he realizes his aunt may not be so crazy after all. Following the clues she left for them, Ryn and Aeden escape back in time to 1930's Arizona, with Ryn on the Orphan Train from the east and Aeden on a railway car with a mysterious girl. Separated by time and space, the siblings are forced to blend into an unfamiliar culture as they try desperately to find each other. Ryn escapes from the brutal family that "adopts" him only to get caught up with a gang of murderers. Aeden is befriended by a streetwise orphan whose values go against everything she was taught. Their only chance for survival rests inside an old mine, but will this be the only clue they cannot find?
