Something that needs to be gotten out of the way: There's very clearly a formula at work here. You're going to see the same pattern of how the relationships shake out in all of the books set in this world.
Each one is still a unique story, and absolutely worth reading. The personalities at play, and the specifics of how things shake out are still compelling when you know basically what is going to happen.
This is a fun story (with some angsty bits - part of the formula) and descends into utter ridiculousness at points, but I wouldn't have it any other way. Highly recommend.
