The silky seal pup - 4

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 the fourth book in the series, a sad little seal pup arrives at the zoo.

But how can Zoe welcome him to the zoo if the zoo might be closing down?
