S. M. Stirling - Emberverse (#1-10)

Dies the Fire (book 1)
The Change occurred when an electrical storm centered over the island of Nantucket produced a blinding white flash that rendered all electronic devices and fuels inoperable. What follows is the most terrible global catastrophe in the history of the human race-and a Dark Age more universal and complete than could possibly be imagined.

The Protectors War (book 2)
It’s been eight years since the Change rendered technology inoperable across the globe. Rising from the ashes of the computer and industrial ages is a brave new world. Survivors have banded together in tribal communities, committed to rebuilding society. In Oregon’s Willamette Valley, former pilot Michael Havel’s Bearkillers are warriors of renown. Their closest ally, the mystical Clan Mackenzie, is led by Wiccan folksinger Juniper Mackenzie. Their leadership has saved countless lives.

A Meeting at Corvallis (book 3)
In the tenth year of The Change, the survivors in western Oregon have learned how to live in a world without technology. But a confrontation between the forces of those who would rebuild the world peacefully and the feared Protector, who will use whatever means at his command to extend his power, threatens to plunge the entire region into open warfare.

The Sunrise Lands (book 4)
A generation has passed since The Change that rendered technology inoperable around the world, and western Oregon has finally achieved a degree of peace. But a new threat has risen in Paradise Valley, Wyoming. A man known as The Prophet presides over the Church Universal and Triumphant, teaching his followers to continue God's work by destroying the remnants of technological civilization they encounter-and those who dare use them.

The Scourge of God (book 5)
Rudi Mackenzie - son and heir of the High Priestess Juniper Mackenzie and the Bear Lord Mike Havel - continues his trek across the land that once was the United States of America. His destination: Nantucket, where he hopes to learn the truth behind the Change, which rendered technology around the globe inoperable. Dreams, visions, and the accounts of those who dared to set foot on the island hint at forces beyond comprehension...and with the competing agendas for the future of the human race.

The Sword and the Lady (book 6)
Rudi Mackenzie has journeyed far across the land that was once the United States of America, hoping to find the source of the world-altering event that has come to be known as The Change.

The High King of Montival (book 7)

The Lord of the Mountains (book 9)
Rudi Mackenize, now Artos the First, High King of Montival, and his allies have won several key battles against the Church Universal and Triumphant.

Artos and his Queen, Mathilda, must unite the realms into a single kingdom to ensure a lasting peace.

The Given Sacrifice (book 10)
Rudi Mackenzie has won the battle that expelled the enemy from the new High Kingdom of Montival. Now he must free the people who live in the state once known as Idaho from occupation by the legions of the Church Universal and Triumphant and pursue them to their lair over the mountains. There he will finally confront the forces behind the Church—the Powers of the Void.

Yet even a victory will not end the conflict forever. The Powers of the Void are malevolent and infinitely patient, and the struggle is one that involves the entire world. They threaten Rudi not only in the present, but also in the future represented by his children, Órlaith and John. Rudi knows this.

And as his heir Princess Órlaith grows up in the shadow of her famous father, she also realizes that the enemy will do anything to see that she does not live to fulfill her parents’ dream....
