Air

They're running out of time. The enemy isn't.

Ancient riddles inscribed in forgotten journals. Four mysterious monuments scattered across the world. A puzzle whose solution could change everything.

Khaly and her family are racing against time—and the relentless Sisters and their Army—to unravel the mystery before it's too late. But the war has left scars, and as frustration builds, tempers fray, threatening to fracture the group when unity is needed most. Meanwhile, their enemies always seem one step ahead, driven by the same goal and an unyielding hunger for power.

As the pieces of the puzzle fall into place, Khaly must hold her team together and face the ultimate question: what lies at the end of the journey, and will it be enough to turn the tide of the war? Air, the thrilling fourth book in the Mechanical Dragons series, delivers high stakes, unexpected twists, and an unforgettable final battle.
