This series of boldly illustrated beginning readers features simple but imaginative stories with a twist: in order to reach the ending, both the protagonist and the reader will have to solve a mystery. Each book includes a bookmark with a mystery for children to solve on it. Bluebeard is a rather unusual pirate: he doesn’t have a wooden leg, a hook for a hand, a weapon of any sort, or a proper pirate flag. If he can solve a few mysteries on his journey, though, he just may find what every pirate craves the most: treasure!
