Just finished Lady of Darkness and I loved it! really looking forward to the rest of the series! I rarely get the attraction to male characters in books but totally get it with this one! I also really understand why people compare it to acotar and SJM's worlds. It has  fae and human realms, a character called Cassius (close enough), a female main character that looks like Celeana Sardothian, trained assassins from a guild, and general SJM vibes... especially in the second half of the book.  but outside of them aspects the writing is much better, the characters feel more real somehow, and the plot seems actually planned out, where SJM's series feel more "fly by the seat of your pants". I also really liked the clearly thought out trauma responses. It wasn't just a thing we were told but the characters actually behaved in ways that trauma causes in people. I think I am rating it 5 stars!
