Elizabeth I of England vs. Mary, Queen of Scots

"British monarch Elizabeth I's long reign is remembered as a period of stability for England. Yet, her relationship with her cousin, Mary, Queen of Scots, was contentious at best, leading to a fatal ending for one of the monarchs. This intrigue-filled volume transports readers into the throne rooms of Europe during the 16th century, where they'll learn of shifting lines of succession, clashes between religions, and assassination plots."--From the publisher.
