Paths to Otherwhere, by James Patrick Hogan. I knew nothing of this author until I had a bizarre Guinness-fuelled conversation with him in Dublin last September. Though the style is a little bald, the ideas are great - scientists research into parallel universes, discover that one of them is a utopia; how does this change them and the intelligence agencies who are monitoring their activities? I kept on thinking of Forever Peace, published the following year and hitting many of the same tropes, and how much better a book it could have been. I will look out for more of Jim Hogan's work.
