Passive Aggressive?

I have been doing a lot of reading all week and i have been coming across a lot of books that stand out...
I came across this ebook for the kindle called -

The Hidden Costs of Passive Aggressive Relationships (The Complete Guide To Passive Aggression) [Kindle Edition]

its only a few pounds so ive downloaded it...
god it sounds so much like a Narc too...

is there a connection between passive aggressive and NPD?

This book is just brilliant , i would advise people to read it...
