Control the Nature (Nature Trilogy 1)

Nature Trilogy 1 tells the story of Cosette, a girl hunted by the rebels known as the Linus Group. These rebels, corrupted by their hunger for power, kidnaps and abuse mages by turning them into subjects of cruel experiments. To them, Cosette was more than a prize- she was the product of a Mage and the Goddess of Nature, which made her more desirable than any treasures.

In their eyes, she's not a human being, instead a living tool, a living miracle they longed to possess.
