Waiting on Wednesday #2: A Breath of Frost by Alyxandra Harvey

Waiting on Wednesday is a weekly feature hosted by Jill at Breaking the Spine. Every Wednesday, we pick a book we're eagerly awaiting and this Wednesday, my choice is A Breath of Frost by Alyxandra Harvey. 

This book was released a day ago and was one that I had been anticipating since last year! Harvey has been one of my absolute favourite authors (and I've only read one of her books!) ever since I read Haunting Violet. I'm looking forward to getting my hands on a copy of this book soon! 

In 1814, three cousins-Gretchen, Emma, and Penelope-discover their unknown family lineage of witchcraft. Beyond the familiar manicured gardens and ballrooms of Regency London, a dangerous, alluring new underworld visible only to those with power is now open to the cousins. 
But unbeknownst to them, by claiming their power, the three cousins have inadvertently opened the gates to the Underworld. 
Now the dead, ghouls, hellhounds-and the most terrifying of all: the spirits of dark witches known as the Greymalkin Sisters-are hunting and killing young debutante witches for their powers. 
And, somehow, Emma is connected to the murders...because she keeps finding the bodies. 
Can the cousins unravel the clues and mystery behind their heritage and power before their gifts are stripped away ...or even worse, another witch is killed?
