The story of the girl behind one of the most well-known novels -- and monsters -- ever, perfectly timed for the 200th anniversary of the publication of Frankenstein.

How does a story begin? Sometimes it begins with a dream, and a dreamer. Mary is one such dreamer, a little girl who learns to read by tracing the letters on her mother's tombstone and whose only escape from her strict father and overbearing stepmother is through the stories she reads and imagines. Unhappy at home, she seeks independence, and at the age of seventeen runs away with poet Percy Bysshe Shelley, another dreamer. She travels to Europe and surrounds herself with more poets and writers, including Lord Byron and John Polidori. On a stormy summer evening, Byron suggests a contest to see who can create the best ghost story. After nine months of daydreaming, 21-year-old Mary Shelley's terrifying tale is published, a novel that goes on to become a very well-known monster story.
