From Lene Kaaberbøl, known as the Danish J.K. Rowling: Book two in the Wildwitch series, an acclaimed new children's fantasy series about a young girl who can communicate with and control the natural world.
Barely recovered from her escapades of the previous year, Clara is just getting used to her new wildwitch identity, as well as to her mysterious new companion, Cat, when she is thrust into a new adventure. First, Clara's friend Shanaia is found badly injured, then Clara's best friend Oscar goes missing - kidnapped.
