A little longer than intended passed before this results post. I hope you have all been managing to sleep okay in the mean time.
SO. The prize of one signed copy of INFINITE SKY and one unsigned/fake-signed [your choice] copy of WONDER goes to...
Simon P. Clarke!
Thanks so much for entering the competition, and taking the time to answer the question, of which blue was better, the blue of the cover of WONDER or the blue of the cover of INFINITE SKY. As I said before, there is no wrong answer, but the right answer was, of course, INFINITE SKY.
[Incidentally, Simon got the answer wrong.]
