For Couples Only Box Set:

Since their debut, these revolutionary guides have sold well over a million copies, been translated into fifteen languages, and sparked much fascinating water-cooler conversation around the country. Now together in the For Couples Only boxed set, these books provide the perfect resource to help you understand what you never knew about the woman or man in your life.

Each volume is based on input from more than a thousand members of the opposite sex—including an unprecedented nationwide survey and hundreds of personal interviews. This innovative approach yields candid and surprising answers about everything you don’t “get” about your significant other—even what that person deeply wishes you knew. It also produces simple but groundbreaking awareness of how you can best love and support the one who is most important to you. [Part of me wanted to make this paragraph past tense—yielded and produced—because of the first paragraph, but that took away some of the immediacy of what the books offer. I’ll leave that up to you.]
So whether you are newly dating or have been married fifty years, get ready to know each other in a whole new way. The adventure is just beginning!
