The Sundered Crown (en Inglés) - Gregory Parrott

The five relics are gathered. The siblings stand at the Precipice of Souls, the very spot where King Atheron first fractured his spirit. But the final ritual is not what they were promised. The Warden-their own forgotten flesh and blood-has revealed the truth: mending the King's soul will not just cure the corruption; it will restore a tyrant who was the corruption's true source.

In this epic conclusion, the heirs face an impossible choice. They can complete the ritual, reviving their father and preserving the ancient lineage of Eldoria, or they can shatter the relics forever, ending the curse but destroying the magical foundations of their world. As the Warden's forces and the King's spectral guard collide in a final, world-altering battle, Corwin, Nyra, Thor, and Eira must decide if they are the healers of a broken legacy or the architects of a new, kingless world.
