Rant includes spoilers and mentions of rape.
I was enjoying this very silly read for what it was: a silly read. Then the ridiculous happened.
I can appreciate the attempt at a style by including the "twas" and "twould"s, but there's zero consistency. It still reads far too modern. The story would've been better without the shoehorned language. Seraphim and Dominique were predictable a mile away; their relationship and their twists were obvious. I also liked Sera a hundred times more before we met her. The legend of the black knight was way cooler before we realized she can't do anything without Dominique. Like, chick can just charge into battle, take (apparently) no damage, and behead a man with ease and then escape from a battlefield like nothing happened? But suddenly she can't even keep a thought in her head without Dominique telling her she's smart? Okay.
Part of Sera's revenge quest comes from her being raped by Lucifer. For a woman who just endured a HUGE trauma, she has ZERO problems trying to jump Dominique's bones. We don't even have a moment where she processes this trauma. It's like, "Gee, I was raped and that was bad. But now there's a pretty man here, and he says I'm pretty, so everything is fine." And then we get the obligatory vomit scene. Despite all of the coincidences to win, despite Sera never learning or growing from anything, I was enjoying my silly book... up until Sera threw up.
So, if you're not following the theme, Seraphim is an angel in mortal flesh; Lucifer is a fallen angel/demon in mortal flesh; oh, and Dominique is a demon-faerie. The mortal-angel was pregnant through rape by the mortal-demon. This puts the author in a tricky position. If the mortal-angel births this thing, it would be a powerful, world destroying demon, but an angel can't exactly say, "Hey, I need to abort this thing to prevent destroying the world. Also, it's the child of my rapist." Now, she could have been given some faerie herb concoction and not connect it to a future miscarriage, but no, no! That would delay a happy ending to this fantasy romance.
When Lucifer is killed, the mortal-angel magically miscarries IMMEDIATELY on some Paris street. She covers it up with some snow and leaves it there in the road, completely unfazed. Um??????
However, the worst, most unforgivable sin of this book was killing Baldwin. The boy did THE MOST in this entire book! They light a candle for him in Notre Dame and that's it. Seraphim and Dominique ride off into the sunset and never think about the kid that did absolutely everything for the quest to succeed.
