A short holiday tweet of thanks

I am getting quite a few messages on Twitter (what? You don’t follow me on Twitter?) and Facebook from folks who got my book for the holidays. To save myself time – I’m too full of cookies and chocolate to do much by way of anything useful today – I’ll say here: enjoy! I don’t know if reading about a gamma-ray burst sterilizing half the planet in under three seconds is a good tribute to Peace on Earth, but who am I to argue with people with such extraordinary taste in holiday gifts?
