This book was recommended to me a few years ago (recommended more due to my interest in various forms of therapy and less because of a personal need for erotic help) and I'm glad I finally gave it a read. I thought this presented a lot of interesting and valuable advice that could really help a long term relationship. While some of the points were common sense (open communication, for example) the author also suggested some ideas that would probably make most couples uncomfortable (discussing an open relationship or flirting in front of your partner are two examples suggested). I could definitely see the benefit in Perel's advice- mostly that you have to continue to date and surprise your partner to keep things interesting. I definitely picked up some interesting tips and enjoyed that she included several real life stories to help explain her couples therapy process. Definitely read this with an open mind since Perel has some unconventional ideas for keeping the spark alive but underneath it all, there is some very good advice for couples to use.
