To be honest, from the title and look of this book, it wasn't at all what I expected. I thought it was going to be in the genre of "mom-comedy" -- instead it is a somewhat amateur attempt at a self-help book for those having trouble in a marriage with children.
I found the book to be more flash than substance -- heavy cover and paper, heavy on the graphic design, and peppered with "dirty little secrets" and "quizzes." I found all of that to be pretty distracting. The quizzes were largely stupid - not really anything you'd EVER pull out a pencil and take (or if you did, that you'd find helpful). They were just somewhat poorly executed comic relief. The dirty little secrets were weird - not so much helpful in any way, but meant just to catch your attention in an "oh my" sort of way.
The actual helpful text was choppy, broken up with little stories and insets, and hard to get through because of it. Their writing style was actually not bad for the meaty stuff, so I'm not clear why they felt they needed to add in all this nonsense when it would have been a nice read without it.
That said, the info, while helpful I guess, was really nothing new. The authors don't appear to be therapists of any sort, but former advertising execs, who pulled together guidance from others along with some basic common sense.
Overall, I was disappointed in this book, although I liked their writing style enough to be interested in checking out their previous books. If you really want some lighthearted basic advice as a starting point, this might be for you. Maybe they'll be one or two points that resonate with you that can make a difference in your life. But I don't think this book is going to save a marriage, or anything close to it.
