It's actually a birthday nod to Mary Shelley, who was born on this day in 1797 - and is, of course, the author of the original book on arguably the most famous monster in history.
Considered one of the earliest works of science fiction, Frankenstein is the brilliant tale of an unorthodox scientific experiment - and the potential consequences of trying to play God.
Mary Shelley's Frankenstein has spawned a complete genre of horror stories, films and plays.
The lore has changed throughout the years, and creative liberties have been taken with the monster's physical appearance, temperament, and even his name. But one thing has remained certain - Frankenstein is legendary awesomeness.
Killer's Instinct, the creeptastic YA book I co-wrote with Judith Graves (October 2013, Leap Books), we take a fresh look at this brilliant monster, offering a bit of a different spin on a classic tale.
What does your Frankenstein look like? And what are YOU doing to celebrate Frankenstein Day? I'm heading to my bookshelf and re-reading Mary Shelley's genius - one of the greatest books of all time.
