I've read the book - more than once - it's great! I've also dropped a carbide lamp in a breakdown pile and had to fish for it. Fortunately I was just a couple of hours from the surface in a local cave - instead of days from the surface, way to hell and gone beyond multiple sumps at the bottom of the world!
I still love my carbide lamps - they're nice and warm in our 48 degree northeastern caves. And good for heating up cans of Dinty Moore beef stew.
