A book written by a fanfiction author - not a fanfiction, thankfully. We don't need another E.L. James. The title reminds me of the Daughter of Smoke and Bone trilogy, Laini Taylor. I actually read the first chapter online (here) before I ordered the book.
A good look at post-change integration between the modern world and the supernatural. That's often skimmed over. We also don't usually get the reaction of the justice system to an infinite number of new ways to commit crimes without technically being illegal suddenly appearing. The vampire discrimination suits were a nice touch.
Chancy isn't writing about people with magic; she's writing about people who are magic. Elementals aren't people who can control an element, they are an element. They use it, and it's not so much a power as a part of themselves, it has expense and gain. Like energy depletion and acquisition in introverts. Demons aren't vague humanoids with an evil laugh and a penchant for murder and mayhem; demons are essence of the infernal, wont to punish sinners.
It does throw you right into the deep end of the supernatural. Tied in with the prose style, you might have a sort of delayed cognizance in regards to anything happening in the text. It might take you a few pages after a sudden event, or a couple of occurrences of an explained magic to properly understand it. My suggestion: pay attention. It's worth it.
The prose is detailed and tight, more so than usual in YA. The premise is good, and the implementation is original. I really liked the depiction of hell. The scripture was a brilliant idea, and I appreciate that it must have taken a lot of research.
Church is...abrasive - I'm a bit too Chaotic Neutral for straight cops to be quite my speed. And abuses of authority, however minor, chafe me. I like the heretics and the ones who make their persecutors burn. Myrrh is my favourite. Her voice is very personable, and she is straight-backed and awesome. I quite liked Sword Aariel, as well, little we saw.
Chancy did a good job of altering the voices of the different POVs; the POV is evident from just the structure and particular vocabulary of the prose. It's a shifting close third. She has a thing for sentence fragments, which make the tone more conversational. I like sentence fragments - I have no problem with that.
Myrrh is obviously old; she speaks very much like an old woman (a very old woman), all archaisms and eloquence. Her voice is refined, but down-to-earth. When she speaks, she expects people not to listen but to move. Also, she's weird.
Church is a straight cop in her mid-twenties with a stubborn streak and an appreciation for the old school. Bad puns, a bit noir. Fighting against industry sexism. She's matter-of-fact, and she obeys the rules and her superiors, follows her gut. She reminds me a bit of Detective Decker from Lucifer (TV).
Aidan has a young voice (apart from the slang and colloquialisms), bewilderment and trauma hidden under teeth and bravado, like someone grinning in fear. He has very obvious ongoing trauma. Something like PTSD: agoraphobia, derealisation, hypervigilance, sensory flashbacks and over-stimulation, hair-trigger startle reflex, paranoia, panic attacks.
Aidan and Myrrh are a good double-act. They have a mutual experience with the supernatural, and they become horrified once they realise what too little understanding and too much liberalism has done to the post-Dark Day world. With only romanticised Hollywood themes and forgotten legends to go on, the modern world has accepted into their midst things more dangerous than they know. They accept beings which are fundamentally other as though they were human, and this is a world gone mad.
The supernatural world operates on fundamentally different rules of nature than the human world. Modern humans, however, with so little guidance, have half-hacked it as though they were trying to integrate another sect of their society. As though the supernatural were a world grown with the human world, reacting to the same things in the same ways. As though the supernatural were just human-plus. It's not. And it's allowed supernatural beings to take advantage of the cultural dissonance.
I suppose it also speaks to the relativistic extremes we've allowed some moral and functional principles to reach. To Aidan and Myrrh, there are some rigid rules by which the world works. There is good and evil, to some extent, and that is not at all relative. There are things you must do, and things you must never do. They've been entered into a world which is not privy to their knowledge, and they are witness to its ill effect. Blood slavery is a life choice; all magic is done by sorcerers. To Aidan and Myrrh, the world is wrong. A hand to them, though, that they've accepted the cultural differences quite gracefully and haven't gone around kidnapping blood slaves and putting cops to sleep for their own good.
A tale of personal responsibility.
