Lightbringer felt night and day different from Night Angel to the point where I also wanted to write a post comparing just the two.

There's a lot of the same tropes but I think Weeks learned to let his characters breath a bit before they become ungodly powerful. I'm Night Angel 1 Asoph becomes powerful by the 3/4th mark and then has 2 more books where he's still that powerful.

I think perhaps the biggest difference though is the world. I really liked the magic system and world of Lightbringer way more than the Night Angel.

Book 1 (The Black Prism) is easily the best of the saga and definitely worth your time.
