One book holds the power to erase humanity forever.

The Fatal Cure is the fourth book in the epic Metalwood Saga series.

In a world torn apart by magic and division, Earth’s future hangs by a thread. The ancient elven race known as the Eldrim rules the surface, wielding immense power from their connection to the Prime Trees, while humanity remains blissfully unaware of their existence. Hidden from the humans, the Eldrim prepare for the ultimate act of genocide: the Soulsundering, a ritual designed to annihilate most of humanity. Only by drastically reducing the human population can the planet survive.

Keya, an elf born into privilege, uncovers the dark truth behind her people’s plans when she stumbles upon the Book of Souls, a forbidden artifact capable of unleashing untold destruction. Her path crosses with Jessica, a human mother fighting to save her son, as they confront the horrors of elven dominion in the mystical city of Sylrantheas.

With time running out, Keya must decide where her loyalty lies: with her people, or with the innocent lives that will be lost. As the ritual begins, both elves and humans must face the harrowing consequences of their choices in a world that will be forever changed by the Sundering.

This heart-pounding book finally reveals the long-hidden answers to how humanity was forced into the sky cities and the devastating events that reshaped the planet.

Can Keya and Jessica stop the tide of destruction, or will Earth fall into a new era of darkness?
