During one stormy summer night, to distract Mary from Percy’s infidelities, Lord Byron suggests they all write a ghost story. All the pain and guilt that Mary feels about Percy, Claire and the child she lost, is poured into giving birth to Frankenstein’s Monster. The story is incredible, a classic that even Percy must acknowledge. But women don’t write books, and publishers certainly won’t print them. The rebel rises, and Mary fights for her creature and her identity, all at the age of eighteen.
