Query: Good book to start for PPP-debug-novice

I need to debug PPP a lot on cisco routers and it gave me a good understanding of the subject. cisco web site has enough info on debuggin PPP and this books goes in conjuction with it along with the relevant RFCs. I didnt find any other book addressing the debugging issues addressed in this book. I'm looking forward to a/the sequel!
