A Mighty Fortress: A Novel in the Safehold Series (#4) Free Audiobook Download by David Weber

In the fourth book in this sci-fi series, the protagonist is now a warrior-priestess who has to take command of her army as they defend their safehold from the encroaching Xoriat.

The action-packed Safehold series continues to follow the story of The Kingdom of Charis as it heroically battles against its sworn enemy in a war of conquest and faith. The Church of God Awaiting musters its forces for a final confrontation with the secular power of the Kingdom of Charis, but its most powerful tool remains unknown: a new god who is literally coming out of nowhere to deliver them from the enemy. This is one final stand that will determine whether or not the Church would be restored as the dominant power on Safehold, or if Charis will remain as an independent nation.

In A Mighty Fortress, Crown Prince Ry of Safehold and his companions resume the journey with their allies, attempting to secure a victory for humanity and end the war at the same time.

Having been snatched from its crash site by the largely unknown but certainly not un-dead Bosun, Captain Maudit and his crew have already almost died once. Now they have to figure out what happened in their absence, and why the ship has so few survivors.
