This is the story of Lia growing up a wretched, or orphan, of Muirwood. The world is made up of several kingdoms which are constantly fighting amongst each other. Mastons are members of the only religeon in the world and are being murdered by the evil king of Comoros. As Lia grows up, she begins to be embroiled in the politics of the kingdom. Eventually she summons the Blight to purge the evil from the world, and she and all of the remaining righteous Maston's flee across the ocean.
This is a fun but fairly light hearted series. It's a transparently Mormon fantasy with priesthood knights called Mastons. Parts were a bit silly like the main character's biggest problem being to stay pure and not kiss a boy before marriage. Overall this was a good page turner.
