I have not been able to put this book down since I got it and I frequently go back and reread some parts. I am in my 20's and its great for my relationship where that always-happy-everythings-perfect-want-sex-all-the-time-phase is starting to slow down, it has alot of good advice to spice things up and I imagine it would be good for people that have been married for many years and need some excitement as well.
