But from the moment Iris arrives at Bosque de Nubes, she realises something isn't quite right. And outside, in the wild and untamed forest, a mysterious animal moves through the shadows. Just what is Aunt Ursula hiding? When Iris discovers a painting named Iris and the Tiger, she sets out to uncover the animal's real identity - putting her life in terrible danger.
