Tiggy Thistle and the Lost Guardians (The Cloud Horse Chronicles, 2)

The Guardians of Magic disappeared ten years ago, leaving the Kingdom of Thrynne in the icy grip of a powerful sorceress. Most people have fled in desperate search of warmer lands, escaping the Ice Monsters that roam the streets. Meanwhile, young Tiggy Thistle lives hidden and safe with a kindly Badger until the day she meets one of the crafty Stiltskin brothers and she has to run from her happy home. So begins Tiggy's quest to find Zam, Phoebe and Bathsheba – the lost Guardians and their beautiful Cloud Horses – the only people, she believes, who can save Thrynne from the curse of endless winter.
