When Great-Uncle Horace brings back lost and homeless animals from his travels around the globe, it falls to Zoe, and her mum, the zoo vet, to settle them into their new home.

She's good at this, because she can understand what they say and talk to them, too. But that's a secret! In this first book, a tiny lion cub comes to stay at the zoo and Zoe must ask Leonard, the grumpy old lion, for his help.
