It was November 2011 when I first read The Two Faces of Tomorrow, and June 2009 when I catalogued Realtime Interrupt (although that was a reread). For some reason, the latter wasn't a 5 star, even though in retrospect it probably should've been. I reread it as part of this collection over this weekend when my daughter was in for surgery and found it riveted me anew, as I hadn't read it for almost 7 years!

Two Faces is slower to get off the ground, but that, also, poses some excellent scientific stuff, especially given its original publication year of 1979. I have very often wondered how much frame of mind and other pressures or indeed even books I've been reading between titles impact ratings, so it's a rare opportunity here to come at 2 books anew. A very worthwhile buy, this, if you're a Hogan fan or not. Recommended most completely for any fan of Hard Science Fiction.
