Query: Tough, like gristles on meat

This story has characters etched in jagged glass. This book is about the cruel and cutting edge personalities. The author writes well, but this cast of characters have no saving grace.The best parts were the descriptions of Boston in the 1960s and 1970s. Anyone familiar with beautiful Boston would at least appreciate that.It's a lucky thing this is a "self-contained" story. It would be a disservice to the world at large if those rotten Hillys, Beas, Bens and Besses came back to haunt you from another book. Like a gristle, this book is hard and tough. Like a gristle, it isn't palatable. Read something else instead.
