This is by far my favourite of Sarah Mussi's books.
Set in Snowdonia, this story follows the heroine Ellie and her friends and a mysterious boy on the mountain.
Sarah Mussi brilliantly weaves together a contemporary setting with with ancient Welsh mythology. You can almost feel the crunch of snow under your feet, the setting is so beautifully drawn.
As you turn the pages you can imagine dragons swooping from the mountain tops.
This story is pacey, thrilling and un-put-down-able. I totally loved it and recommend it to all readers who love contemporary fantasy and magic.
