Lucy Granger is settling into her new life as a permanent tenant on New Moon Lane. Her picture book about Llarry and the other animals has been published, and she has even maintained the unusual friendships she has formed.

The unexpected is still prone to happen, however. Lucy receives a series of unusual greeting cards addressed to the llamas, revealing another unusual part of the farm's story. It also introduces her to the precocious and persistent Princess Hannah, who wants to change Lucy's way of thinking about the animals' former purpose.

Meanwhile, Lucy's attempts to find Kenny the cockerel a companion only creates troubles for herself, whilst also bringing three more troublemakers under her metaphorical wing. And the young vet Arthur Elliot makes a medical observation regarding Philly's health, which requires a Christmas miracle.
