Writer H.P. Lovecraft died in 1937 at 46 years old, with poverty and malnutrition being contributing factors to his early death. It’s with that in mind that Ross Lockhart, the editor of The Book of Cthulhu, came up with a 24-hour Twitter challenge to help feed the hungry. This Thanksgiving, if you donate to a food bank or any charities that help feed the hungry, you can enter to win The Book of Cthulhu, an anthology collecting 17 tales of cosmic horror inspired by the writer Lovecraft.

To enter to win, make your donation, then sign on to Twitter and tweet the following message:
