If I were to summarize this novel in one sentence, it would be:
This is a story about a vampire, named William Shakespeare, who falls in love with a human, named Kate,.... while they both fight off an army of zombies in 16th century London.
No matter how it sounds, this is a romantic tale. William Shakespeare is a vampire, one of the undead. And Kate is a chasseur, a huntress who kills zombies and vampires and anything else supernatural. The two meet when they travel the streets of London at night, hunting for zombies which started to appear in the city.
Together they must defeat the zombies and find the necromancer that is summoning the army. Meanwhile, Shakespeare must try to keep his undead secret from Kate, or she'll chop off his head when she finds out. That's going to hurt a lot more than just being kicked in the nuts.
This is a great tale full of romance, sex, blood, zombies, and Queen Elizabeth. How can you not want to read this book?
P.S. - Throughout the book, there have been scenes that vaguely implies that Shakespeare will continue to live on and write other works in the 20th century, such as The Wizard of Oz, The Sixth Sense, Star Wars, etc....
