The Death of the Good Wizard

Book 2 in the award-winning and highly-praised Red Monocle series. Middle-schoolers Gregory Guest and Yolanda Torres didn't expect to use their strange lenses to return to the King Arthur story. But when their friend from that other world goes missing, they're afraid he will accidentally destroy their own reality. When the Taker and the Keeper travel back through the eerie tunnel, they find themselves in a completely unexpected story and a reality full of new dangers - including one very persistent dragon.
