Happy Holidays! Have a free copy of my book!S

I'm celebrating winter by giving away ten free, signed copies of my science nonfiction book Scatter, Adapt and Remember: How Humans Will Survive a Mass Extinction. Everybody wants apocalypse and extinction at the holidays! Here's how to get it.

At noon PST, I'll tweet a very easy question from io9's Twitter account, and the first ten people to answer will win free copies of the book, signed and dedicated to the person or thing of your choice. I'll send it to you, no matter where you are in the world. You must be following io9 on Twitter to win, because I'll be contacting winners by DM.

This is a book about all the mass extinction level disasters that have befallen the Earth, as well as how we'll survive similar disasters in the near future — and what we'll evolve into in the far future. Or, if you like to watch, can see me talking about the book at Seattle's Town Hall, in the video below!
