The first three books have some decent reveals, interesting enough to keep me reading. But the last two books were an awful slog to get through. There's a really obnoxious preference for telling over showing, with the narration explaining ad nauseam how characters feel when it's perfectly obvious how they feel.

Also, it feels, oddly, like a young adult novel. That's not necessarily a bad thing, but the characters are all adults and yet they feel like teenagers. It's a weird dissonance when someone's age is mentioned, because they don't feel like they should be that old.
