I received an advanced copy of this book from the publisher via NetGalley.

Oh man. What a great tie-in to Melissa Albert's Hazel Wood series.
Set in the Hinterland, this book is a series of "fairy" tales that give backstory to several of the characters in the main series. A collection of short stories, each more sinister or horrific than the next, it can be read as a stand-alone. Perfect for those who do not need, nor want a happy tidy ending to their tales.
