Polly's own family, the Kershaws, provide all the support they can, but they are unable to outmanoeuvre the malicious Dr Browning-Baker, who is determined to have Billy taken away from the young mother who has dared to defy the doctor. This would deprive Billy of the exercises and stimulation that are his only hope.

Forced to flee to the Fylde coast, Polly and Billy find shelter with another damaged family - an ex-Army captain whose First World War marriage was a terrible mistake, and his daughter, who has never recovered from the hostility of the mother she loves. But danger threatens the fragile happiness they build there.

This is how Our Polly's cover was developed. The artist (Nigel Chamberlain) was given information about the story, then drew the rough concept sketch shown here. From this, he developed a painting in full colour. The publisher's art department then puts the necessary information on the cover, including the blurb, and information about the author and her other works. For hardbacks there is usually a photo of the author and a bio, ie a mini-biography.
