'Don't stray into the Quartermile Field. Any animal with sense avoids the spot,' warns Sammy's mother. But Sammy is curious - about the Field, and about his father, the fierce, wild father he's never met. Then one day Sammy discovers that his father has returned. And determined to track him down, Sammy sets off towards the strange, wild land of Quatermile Field - and into a very different and dangerous world . . .

A sequel to "The King of the Vagabonds". Winter has come. Leaving Sammy behind, the other cats have gone to find shelter and better hunting grounds. Out scavenging for food, Sammy and his companion Pinkie find themselves trapped in a delivery van speeding towards an unknown destination.

The final part of a trilogy that began with King of Vagabonds and City Cats. Life in the London park has been easy and peaceful for Sammy, Pinkie and their three kittens, but all that is about to change. There's a purge on stray cats and dogs, and Sammy and Pinkie face the question of survival.
