The Heir

The battle for the future of existence has begun.

William, the Prince of the Seven Heavens, has vanished, leaving the System of Universes on the brink of collapse. Ancient enemies emerge from the shadows, alliances are tested, and the fragile balance that has protected countless worlds begins to unravel.

But hope arrives in the most unexpected form.

Born from the impossible union of Light and Darkness, a child known only as the Heir is destined to become the most powerful being the System has ever known. Yet he remains vulnerable. For twenty-one days, his extraordinary power lies dormant, and during that brief window, the fate of every universe hangs in the balance.

Determined to prevent the prophecy from coming to pass, the High Demon Kenun unleashes his deadliest weapon to hunt the child before he can awaken.

Now Isabel and Zagreus must protect the Heir while navigating a dangerous web of ancient prophecies, celestial politics, forgotten civilizations, and impossible sacrifices. As the boundaries between mythology, science, and reality begin to dissolve, they uncover secrets that could forever change the destiny of every world.

The Heir is the fourth installment in the Isabel's Bridges saga, an epic blend of science fiction and fantasy that combines mythology, cosmology, romance, quantum physics, and adventure into a sweeping tale of love, sacrifice, and destiny.

Perfect for readers who enjoy expansive world-building, immortal heroes, parallel universes, and unforgettable cosmic adventures.
