I really enjoyed this one. Here we have Will on his own quest all alone.
After suffering an illness he is sent to his aunt's in Wales and the quest begins.
I love the back drop of the Welsh country side and the side characters were all fabulous.
We also get to meet Bran one of my favourite characters of the series. He has suffered the most of all the questers and yet he keeps going. I felt so much for him in this one. 
Will actually has to use his brains in this one and as he learns about the Welsh country side unearth the clues from the terminology. It was a great way to include local legends into the story

Great addition to the series, now onto the final book.
