The Young Elizabeth. Now in favour, now out. Accepted by three step-mothers, a thorn in the conscience of her father, King henry VIII. From the age of eight, the mercurial young Elizabeth found royal courts were dangerous places if one wanted to keep a head on one's shoulders. As she grew up, so did the dangers surrounding her increase. Elizabeth knew that one false step could lead to Traitor's Gate and the block.
Eleanor Alice Burford, Mrs. George Percival Hibbert was a British author of about 200 historical novels, most of them under the pen name Jean Plaidy which had sold 14 million copies by the time of her death. She chose to use various names because of the differences in subject matter between her books; the best-known, apart from Plaidy, are Victoria Holt (56 million) and Philippa Carr (3 million). Lesser known were the novels Hibbert published under her maiden name Eleanor Burford, or the pseudonyms of Elbur Ford, Kathleen Kellow and Ellalice Tate. Many of her readers under one penname never suspected her other identities. -Wikipedia
I've not actually read this in years, but it is a treasured possesion, being a gift from my godmother when I was a very small child. I know I loved it back then and read it again and again.
