After finding the Palace of Polar and escaping the Pyramid of Trix, it's time for our heroes to go back to school. But there is still a threat. Calvin and his friends must protect Trident's key from falling into Ovalore's hands. And with their new friend, maybe they'll succeed. These books are kind of like Percy Jackson, but I created my own characters and an entire pantheon. Not even Riordan could dream up such a feat (or maybe he could).
