LOVE LOVE LOVE THIS BOOK. Guys, it was SO good. It was probably the best new book I've read in a long while.

A Breath of Frost takes place in Regency London and centers around a debutante named Emma Day. Along with her cousins, Gretchen and Penelope, she comes into her powers of witchcraft quite unexpectedly one night at a ball. It turns out that the three cousins come from a long line of powerful witches and due to unknown reasons their powers were bound. All sorts of things start to go awry, like young girls being murdered (and Emma being the prime suspect), gates to the Underworld being opened, and a truly wicked trio of warlock sisters, the Grimalkins, to be unleashed. Emma, Gretchen and Penelope have to figure out how to use their powers and defeat all the evil before it's too late.

I adored everything about this book. Emma was a completely relatable main character but my favorites were Gretchen and Penelope. They were unbelievably sassy and unwilling to form to London society's ideas of how a debutante should act. The love interest, Cormac, was interesting and swoon-worthy without being overbearing or suffering from insta-love. I loved that it was about London during debutante season but also about witchcraft. It was an unlikely pairing but ultimately perfect. The plot was action-filled and never got dull for me, even though the book was almost 500 pages long.

In a lot of ways it reminded me of Gail Carriger's Parasol Protectorate series but more geared towards the YA audience.

GET IT RIGHT THIS SECOND AND READ IT. I'm not kidding. You will love this novel!
