It's always nice when a reader tells me s/he enjoyed one of my mysteries, but some compliments really stand out.
A woman home-schooling her thirteen-year-old son told him to read the first part of The Ragtime Kid, then report to her on the use of language in the material. When the boy finished that portion of the book, though, he didn't want to go on to his next assignment because where he'd stopped, a group of bigots seemed to be getting the upper hand, and he couldn't wait to find out what was going to happen. His mother agreed. A while later, her son ran up to her, waving the book, and shouted, "All right! Those sons of bitches got exactly what they deserved."
I'll be grinning for a while.
