During one such visit, news reaches Ben, the Greenblooms, and their friends that the last Pegasus in the world has been discovered. The legendary horse has three unhatched eggs with him, but the only way they’ll ever hatch—and continue the survival of this incredible magical species—is if they are placed under a griffin’s feather. But griffins are the most dangerous creatures in the world, and their mortal enemies are dragons.

Ben has vowed not to tell Firedrake about his quest, in order to protect him. But as he and the Greenbloom team set off for a remote island where the terrible griffins are rumored to live, he may end up needing the help of his best friend—and dragon.
