Everyone has their own concept of what "monogamy" means—and most people assume their partners and spouses are on the same page. Couples may assume that they are monogamous, but never discuss exactly what the monogamy agreement means to them. What happens when this implicit agreement is broken? After infidelity, relationships can become strained as both partners lose trust and faith in each other.

Author Tammy Nelson helps couples regain trust, romance, and intimacy after infidelity by redefining the monogamy contract. The new monogamy contract is an explicit relationship agreement created after the affair that allows each partner to safely share their desires, expectations, and limitations. This agreement does not create an open marriage, but rather, an open conversation wherein each partner can have a say in setting the ground rules for their relationship. 

The book first helps couples rebuild trust after the affair, then engages in a series of imago dialogues based on questions about what each partner really wants in the relationship. Then, the book helps couples make a recovery from infidelity by addressing erotic problems that may surface and offers advice for helping couples return to desiring and trusting one another. After an affair, it's impossible to go back to the way the relationship was before, but this book offers the chance for a new beginning.
