20,000 people have read this book--a small town--but because it was GRISHAM, most of them were sucked in. no legalistic drama. no court room showdowns. no explication of mechanisms by which to cheat the system.
hence, low ratings on GR.
HOWEVER... if you don't actually like Grisham, this is the one book you might actually like. this and his short stories were fun. the rest, I find, somewhat unreadable
