The Guide To Lasting Love: A Therapist’s 21-Day Program To A Fulfilling Relationship is a blueprint for how a couple can improve their relationship. This Guide can be recognized under the self-help/relationship genre and is specifically targeted to support busy couples between the ages of thirty-five to forty-five. In this stage of a couple's life, child-rearing, career-building and other caregiving responsibilities compete with relationships, displacing the focus on relationship-building and personal growth.
