The Decoders in The Magic Sapphire
by Alba Arango
Steve, Matt, and Jenny always dreamed of being detectives. One day, the twelve-year-olds’ dream becomes reality when they discover an ancient treasure map written by a pirate over three hundred years ago. As the investigation leads them to a string of hidden caves filled with booby-traps, they are confronted by a jewel thief who comes up with his own plan to force them to find the stone for him.
