Query: I want my money back

I have been in IT for 11+ years and recently started moving into the client-server area.This book was used as a college prescribed book for my last semester (not enough copies of the regular book were available) but was so bad, even the lecturer stopped using it. We were told to borrow object oriented powerbuilder books from the library instead and this book was removed from the curriculum.
