Once upon a time astronomy, astrology, and religion were all the same thing - and to the characters in this book, sometimes they still are the same.
Irene is an astrophysicist working with particles to create miniature black holes in her lab. George is a cosmologist trying to prove the philosophical concepts of the universe as explained to him by the gods and goddesses who visit during his headaches. They couldn't be more different - except that when they meet, it seems the stars collide and planets realign.
Lydia Netzer does a wonderful job with scientifically geeky characters (see also her book Shine, Shine, Shine). This couple banters about physics and the cosmos in a way that truly makes it almost sexy. They're a great match; which was expected, because their mothers planned it so.
I had three different theories on what I thought might happen at the end of this book, and I was wrong. Satisfyingly wrong, even. What an odd, wonderful book!
