Would you like a signed copy of Before the Lights Go Out, my new book about the future of energy?

Between now and the end of April, you can earn a fun prize for telling other people about my book.

Buy Before the Lights Go Out and tell people that you're reading it on G+ (or Facebook, or Twitter, or whatever social network you prefer). Tag me in the post, to make sure I know you mentioned the book. In return, I'll send you a sticker with a signature and personal thank-you. You can put it in your printed book and create an instant signed copy. Or, if you're an e-book reader, you can put the sticker on something else, I guess. Either way, it's yours!
