It's about twins who were conjoined at the head and separated after birth, born in a hospital in Addis Ababa to an Indian nun. They were brought up by an Indian couple living and working at the hospital.
We wondered about the name. "Cutting for stone" is in the Hippocratic oath so we knew that was part of the reason for it but we weren't sure what the phrase actually means. One member said it meant quarrying, searching for something, which made sense.
Our discussion drifted when we started talking about the way the two boys in the novel would fall asleep with their heads touching, as they'd been in the womb. We started talking about sleeping with our siblings and having our kids join us in bed. My kids all learned to go to Randy's side of the bed because I couldn't take their wiggling around and bumping me.
We all liked the character Ghosh a lot. He was like the boys' father, although not their biological father. He was a rock, everyone could rely on him and he always had sage advice.
I recommend this one, too.
