By the Angel, that epilogue made me gasp aloud. Whilst I did enjoy the book (hence 4 stars) I do think there were some pacing / character / plot issues that could have been ironed out.

Spoiler

Things I liked first:
★ Satisfying ending for Emma & Jules, even if it was predictable. She was never going to kill one of these two off or have it end with them exiled.
★ Drusilla growing into her skin and seeming content at the end.
★ Magnus & Alec's story... loved it (though I wouldn't have minded if this had been kept to their own books that I keep hearing about!)
★ The isolation of Idris and the implications this will have on future books - great stuff.
★ Certain aspects of Thule were really interesting. Sebastian's line of 'I prefer redheads' gave me chills.

Things I wasn't so keen on:
★ The book did not meet certain expectations. For instance, if you're going to build Anabelle Blackthorn up as an awesome villain in the second book, call the third book Queen of Air and Darkness and have her be the focus of the cover art, maybe don't have her be completely flaccid and kill her half way through. Maybe it's just me, but she ended up being utterly pointless to the story.

★I enjoyed the quarter of the book that was set in Thule, not because it had any bearing on the wider plot IN ANY WAY, but because it was all told from Emma's and Julian's perspective, which meant a break from the constant perspective juggling of the 18 or so characters. It felt like the author was trying to do too much. It didn't need to be 900 pages to be a good story with a satisfying end, but that's what you end up with when the author is trying to:
- create arcs for the 8 or 9 arguably main characters
- introduce a fleshed-out transgender character
- create a polyamorous three-way relationship tastefully
- juggle too many locations and worlds. We're in LA, now we're in Idris. Back to LA. Quick stop in Faerie. Whoops we've hopped a portal to Thule. The Scholomance. The Silent City. The Shadowmarket. Jesus Christ.

Finally, I feel like it would have been a much shorter book if she didn't feel the need to pay fan service over and over and over and over and over again. I love MAlec and Clace as much as the next Shadowhunter obsessed individual but even if this book had been TWO HUNDRED pages shorter it would still have been a long book. I don't need the TMI characters to turn up in every book to fulfil me as a reader.

I'm likely to read the other books she's got coming out, mainly because I do genuinely love this world.
