Rival Queens: The Betrayal of Mary, Queen of Scots

Mary, Queen of Scots & Elizabeth I of England. Two powerful monarchs on a single island.
Threatened by voices who believed no woman could govern.
Surrounded by sycophants, spies and detractors.
Accosted for their dominion, their favour and their bodies.
Besieged by secret plots, devastating betrayals and a terrible final act.
Only one queen could survive to rule all.
