What a wonderful, terrifying and frustrating book! I have a term that I made up when I read this book: Nineties Drama Anger. A special kind of frustration and anger felt for protagonists of (usually) books and movies from the nineties when they are abandoned by friends and family and disbelieved. I remember feeling this level of anger for a fictional character when I was younger and watching A Little Princess.
ANYWAY, I felt this for our poor protagonist Patricia.

And when you find out about the husbands and what they were up to behind the wives' backs? I was seeing red! Hear me, husband of mine, if you ever pulled a stunt like that, don't expect me to meekly step down and let you tell me how to live my life and raise our kids! Oooooh, I'll {redacted}!!!

This book was very similar to the plot and feel of Fright Night, and also a wonderful book by Mary Downing Hahn called "Look for me by Moonlight". I great book with a very mean, bad vampire man. And a group of mothers that are more than just housewives drinking wine at a bookclub.
