Isekai Tamer Book 4: The Holy Knight and the Fallen Justice

Book Description for KindleA Holy Crusade is marching on his paradise. To save his family, he won’t just defeat their champion—he’ll claim her.

Ethan’s sanctuary, Aethelgard, has flourished into a home for the hunted. But peace has painted a target on his back. The Holy Order of Ordin, a fanatical army led by the invincible "Lion" Gideon, has declared a crusade to wipe Ethan’s "impure" kingdom from the map.

With his powerful allies forced to withdraw, Ethan and his family of monster girls are left isolated and outnumbered. Their only hope is to fortify their home and hold the line against an army of five hundred.

But the Order’s vanguard is led by a nightmare in white a Dullahan.

Isolde is a headless knight of unstoppable power, bound by a curse to serve the Order as a mindless weapon. She feels no pain, knows no mercy, and cannot be killed. But where others see a monster, Ethan’s 【Divine Eye】 sees a victim—a woman trapped in a cold, iron cage, crying out for warmth.

To stop her, Ethan must launch a desperate heist into the heart of the enemy camp. His to steal her severed head.

But breaking her curse requires more than just magic. It demands a transfer of life force so potent, so intimate, that it will shatter her holy vows and rewrite her very soul. Ethan must fill the void within her, turning the Order’s perfect soldier into his own devoted guardian.

The Lion may have brought an army, but Ethan is about to unleash a Fallen Saint.
