A Mighty Fortress by David Weber (Safehold 4)

After reading the snippets since January my most anticipated book of the year arrived. I am a long time fan of David Weber and the Safehold series. Genocidal aliens, a Humanity that hides on the planet Safehold ruled by the Corrupt Church of God Awakening and an android with the mind of a long dead starship captain with a mission to restore civilization.

This is the fourth book in a series that started with Off Armagedon Reef where Niume Alban wakes up, asses the situation decide to back the kingdom of Charis for their enlightened royal family and general inventiveness. After a sex changing morph she dons the identity of Merlin a Sejin warrior, save prince Cayleb from assassins, becomes his bodyguard and start to change the way they think.

The Church lead by the greedy and power blind Group of Four conspire to send a fleet to destroy Charis. They are defeated by the new and improved fleet of Charis Off Armagedon Reef.

In By Schism Rent Asunder the church retaliate and massacre Charis’ unarmed civilian traders and their families. Cayleb now king, retaliates by sending a fleet half way around the planet. He also makes peace with Chrisholm, falls in love with their queen Sharleyan and in their Marriage create the New Empire of Charis, united against the rest of the world.

In By Hersies Distressed it is Charis turn to go on the offensive, invading the island princedom of Corisade. Charis get to show up their new and improved army and artillery before they defeat prince Hektor’s army. Hektor is killed by church assassins. His son and daugther flees to exile with thoughts of revenge on Cayleb who they believe killed their father.

We have also learned that there is an Order inside the church that knows the truth about Safehold, that their religion is a fake and that suppression of scientific methods and innovation have been built into their society by the former colony founders. Now Cayleb, his wife and a few others know the truth. The brothers have an elaborate procedure before approving any new member and they are frankly scared of the rapid changes.

There is yet another group, the Circle, inside the Church that doesn’t know the truth, but they oppose greed and corruption inside the church. But they have been betrayed by one of their own when A Mighty Fortress starts. The only question is when the Inquisition will strike

World building

This is the kind of story David Weber does well, take a backward planet and introduce modern science and technology. You notice his extensive knowledge in the details. You get the world by short narratives with local points of views that makes the world come alive with people you care for and understand.

The Church of God Awakening didn’t exist at first on Safehold, it came after a schism where part of the crew of the colony ships decided to create a technological enclave only to be exterminated by orbital strikes, in retaliation they set off a nuke at a meeting of the colony leadership, that had set up themselves as God’s Angles. The Church was created in the following years and it took it’s seat in the city of Zion and it’s mysterious Church complex made out of battle steel. It gives off mysterious energy readings so Merlin keeps his spying remotes out of it. Thats about the only place of power on the planet he keeps them out of.


The church is building an armada using the lessons learned from previous failures. This time they have almost the same technological level as Charis, at least until Charis new explosive projectiles enter production. The Charisian’s are hard pressed but their experience and training still gives them a significant advantage, that might not help if they are outnumbered three to one.

Charis also have to deal with attempted insurrection in Corisade, the princedom they defeated in book three. One of the leaders of the underground is the silversmith Paitryk Hainree (Patrick Henry, Give me Liberty, or give me Death).

There are also people inside Chrisholm that are not happy about the New Church of Charis some of them might even betray them.

The group of four tightens their grip on the church and a wave of arrest sweeps through Zion, while Merlin attempts to save as many family members and sympathizers as he can.

In an attempt to avoid fighting the combined fleet of the church, Cayleb sends off one of his best commanders on a mission to intercept one of the fleets before it can unite with the others.

The Navy really have to show their color here, they are the wooden walls of the fortress defending Charis, and A Mighty Fortress it is. But the big clash still lays ahead.


This is very much a character driven story. At the back of the book there is a 22 pages list of characters you might find useful if you are new to Safehold or need to catch up, My first thoughts at that was wow, this is like one of those old Russian classics, but don’t worry the main characters are not that hard to keep track on.

This is a space opera, so the characters are competent, they are not invincible and they are all easy to love. For example Queen Sharleyan is pregnant so Merlin brings her up in space on their way to a medical exam in his base in The Mountains of Light. She is the first human in space for centuries and her marvel is a delight to read. Another highlight is when they tell their Spy master and his wife the truth.

Weber has a thing for good persons doing evils bidding out of duty like Thirsk, the enemy fleet commander or Hektor’s daughter who believe she has to revenge her father.

Merlin gets to shift around a bit more in this book, he takes on the identity of other ‘friends’ of his to help with the evacuation in Zion and to visit other rulers in their bedrooms and chat a bit. It is all done with a great deal of humor. I also like that Merlin doesn’t solve all the problems himself, he can’t. In fact it can kill.

My View

A Mighty Fortress is a magnificent military science fiction saga and I like it a lot. But there is much back story, meetings and character development is this book, that might not be for anyone, I like it quite well though. If you are looking for an action packed military action kind of novel this is not it. We are still waiting for the big fight here, that will probably be in the next book, expected 2011.

If you are new to Safehold you should start with the other books, the back story is quite extensive so you should read it first. Otherwise I would recommend it to any lover of Weber or Space Opera, as long as you don’t expect fast and action packed.
