Not all sequels work but this one does and how!
This time around, it is not Dee who is pursued by 'Them', but James. He and Dee now attend the prestigious music school Thornking Ash where he is pursuing his dream to become a better Piper (bagpiper).
He has unwittingly attracted the attention of one of the Leanan Sidhe who are Faerie but not quite Faerie (yes, that's right) and are also deadly to humans. Their aim is to give you something like inspiration for your music and in return you give them some of your years (life).
If you love Celtic mythology and lore and of course stories about the Sidhe then you will find this book utterly irrestible. It has elements of love, hatred, resentment, bravery, forgiveness in it plus a whole load of horror although not the slash, maul genre. It is both threatening and mindblowing.
Maggie Stiefvater certainly knows how to weave a story so expertly that you will want to read this book in one go and then you will be sorry when you have finished it. I am hoping that she will maybe turn this series into a trilogy.
