Grey Griffins: The Clockwork Chronicles: Relic Hunters No. 2

In this second book in the Clockwork Chronicles trilogy, the Griffins face one of the most challenging tests ever-maintaining friendship after a tragedy. Life at Iron Bridge Academy continues, but things have changed. Ernie, a changeling (half fairy with immortality and super powers) has been distant ever since a fellow student and changeling was killed by Otto Von Strife. Instead, he prefers to spend time with other changeling classmates and together they form a vigilante group to capture changeling kidnappers. When Ernie's antics get him into trouble, the Griffins are forced to rescue him, endangering all their lives. Their united quest to capture Von Strife eventually brings the Griffins together again. They must overcome killer clockworks, spider-like beasts, and an army of animated dead to track down their nemesis and stop him from building The Paragon Engine, a machine that will open up a portal, allowing monsters, predators and other unthinkable creatures into our world. But with the help of a powerful robot suit, a sleek new stealth plane and a glimpse into Von Strife's secret past, the Griffins might just find him after all
