Geoff Robbins runs the book blog Cool Science Books.  He was kind enough to review The Sky’s Dark Labyrinth here and has just published an interview with me about the writing of the book.  It was great fun answering Geoff’s questions, especially as we veer off into such territory as how I got to taste Galileo’s favourite biscuits and whether I had made the character of Tycho Brahe a bit too over the top to be believable. Geoff's most interesting question was about what Kepler would have made of modern cosmology.  I was tempted to say he would be utterly thrilled by it, but then I started to really think about it.  In the end, I opted for a completely different take.  Read the full interview here.
