This is one of the books in Meyers' Young Royals young adult series, the one about Queen Elizabeth I of England.
In order to appeal to young readers, Meyers gives many sordid details of Elizabeth's young life. After her father, King Henry VIII, dies, Elizabeth survives lots of rumors (and truths) about her lineage. Caught in the middle, she watches as Queen Mary (the legendary "Bloody Mary") takes the throne.
The book changes course here and concentrates on Elizabeth's torture under Mary's reign. As a Protestant, Elizabeth is ridiculed, insulted, and eventually imprisoned in the famous Tower of London. After being forced into allegiance to Catholicism, Mary dies of illness. Elizabeth ascends to the queenship.
In conclusion, it is important to note the lack of historical accuracy with one part of the book. That would be Elizabeth's relationship with Thomas Seymour. The book suggest that they have an extensive relationship. The truth of the matter is that Thomas Seymour tried to seduce young Elizabeth before she became Queen. However, nothing came of that relationship.
