Hey, I started Night Angel pretty recently too. I'm on audiobook while walking to classes and such, but I am enjoying it a lot so far. Definitely darker than most of what I've read. I read what is out of the lightbringer series last semester and enjoyed those a lot, waiting for the next one not so patiently.
My bedtime audiobook listening is 15 minutes of Wheel of Time though, I like something familiar when I'm trying to sleep -- it helps me calm down. It may take me a while to get through the series at that rate. We'll see how long I last before binging it at double speed all day, haha.
