Query: Very helpful!

This book is great - the authors are down to earth but not dumbed down, they are knowledgeable and intelligent but not so collegiate that you can't identify with them. They do really well, I think, in helping the reader understand the selections of literature they've chosen and challenging you to think out of the box. They do a great job defining the terms used in the study of literature / writing as well.
