If you want to participate, you just have to write any word, emoji or punctuation mark on this post.
There will be just one winner on the Instagram post and another one on my Facebook page, that will receive home a signed copy of the book. You can participate as long as you’re lucky enough to have a postman happy to do his /her job. You won’t have to pay anything.
Good luck to anyone! You have until December the 8th!
