"Our Dark Duet" by Victoria Schwab
I very rarely read a series in order, but this one was too good to read out of order. I listened to both This Savage Song and Our Dark Duet on audiobook. Every single aspect of this duology is perfect. The world-building, characters, plot, and more are exceptionally done.
The world-building is completely original. Violent acts breed violent monsters. So when there is a murder, a monster is born to cause more destruction. This concept continues into Our Dark Duet perfectly. I don't want to say too much because I think you should experience it for yourself. But this book is so much more than that. The buildings, subways, and cities are all constructed in a unique and intriguing way.
The characters are absolutely everything in this book. They both have tragic backstories, without it being a cliche. And you also don't get the stereotypical male-female lead romance. I loved that. It showed that their friendship was so much more. I thought it was beautiful, and I wish I could read more books with a similar dynamic. The only other book that I can think of like it is Schwab's adult fantasy series, A Darker Shade of Magic.
And the writing. Oh, the writing is absolutely beautiful. It is poetic yet descriptive. I could picture everything as if it was happening right before my eyes.
I can't say more positive things about this duology. This pair of books is worth every ounce of the hype, and I highly recommend them to everyone, young and old.
About the book:
"THE WORLD IS BREAKING. AND SO ARE THEY.
KATE HARKER isn't afraid of monsters. She hunts them. And she's good at it.
AUGUST FLYNN once yearned to be human. He has a part to play. And he will play it, no matter the cost.
THE WAR HAS BEGUN.
THE MONSTERS ARE WINNING.
Kate will have to return to Verity. August will have to let her back in. And a new monster is waiting—one that feeds on chaos and brings out its victims' inner demons.
Which will be harder to conquer: the monsters they face, or the monsters within?" (Goodreads)
