Beware - somebody on your faculty recommended that book to a textbook committee, either because he or she (note the "diverse" usage there) knows the authors (true much of the time) or because he or she doesn't see anything wrong with it. (Or, worse still, because he or she hasn't read it. That happens more than you'd like to believe).
But don't panic. You do have an antidote - FR.
Thanks Bill. When I read it, I took a deep breathe, and came here and posted it! LOL!
