The launch of a brand-new series from blockbuster Warriors author Erin Hunter about two orphaned cat sisters who discover a secret world of magical creatures . . . and the humans who are out to control them.

Willow and Luna have been on their own since they were kittens. After their mother's death, they settled into a scrappy life in the heart of the city. But when a mysterious fire rips through their makeshift shelter, they're left searching for a new home.

Luna is immediately drawn in by the strange, secretive animals they meet in the park--animals they can somehow talk to . . . and who unlock her ability to perform magic. Willow is less sure about these so-called "attuned" animals and has no interest in joining their world--or their fight against the human witches who seek to "bind" the animals to them.

As Luna and Willow come to realize their own unique magic, they find themselves at odds, separated by destiny, with the fate of the whole city in their paws.
