The Shield Ring

Blurb

The Shield Ring is a historical novel for children written by Rosemary Sutcliff and published in 1956. It is the last in a sequence of novels, chronologically started with The Eagle of the Ninth, loosely tracing a family of the Roman Empire, then Britain, and finally Norse-Britain, who inherit an emerald seal ring bearing the insignia of a dolphin.
It takes place during the Norman Rule of Britain, and tells the story of resistance against the Norman Conquest in the Lake District and North West England. Like many Sutcliff novels, the story of the characters unfold against a background of multi-cultural conflict and change.
