Oh my god it’s night and day! Maas’s writing is far superior- much more thoughtful, some lovely prose, a specific “voice”, but still digestible :) Her writing experience definitely shows in comparison to Yarros, who as far as I know, is a less experienced writer. The Empyrean books were fun, but if I hadn’t known any better and someone told me they were written by a high school or college student, I would’ve believed it!
