I was recently tagged on a Twitter post in what has been called the Book Challenge. If invited, the recipient is asked to post a cover of an all-time favourite book, with no explanation or description of the choice. Just seven covers over seven days, and with each post the recipient is asked to nominate someone new to take up the challenge — a chain letter, of sorts, for the 21st century. 

Are you afraid of the dark?
