Fifty Shades of Faithful - Fifty Shades of Faithful, #1

Trust the Tuckers -- A cop and a photographer husband and wife team who are not your average relationship counselors!1. Sam helps a young man who risked his marriage to try a little role-playing. 2. Vivian tells Sam to get tough with a two-fisted female taking out her money pressures on her husband. 3. Sibling squabbles continue beyond the grave when a friend of Sam's accuses his brother's former caregiver of being a gold digger.
4. The Tucker's housekeeper needs their help to survive adultery and a family secret the women have kept for generations. 5. When child traffickers show up at Vivian's  photo studio, she and Sam deal with a couple whose relationship might endanger themselves and the children they hope to rescue. Free of graphic or explicit content, this book still has some eyebrow-raising bits of advice about trust and honesty, playful communication, and gentle roleplaying within marriage.
It's not a sex manual, and it's not just for married people, but for people of all ages and stages of life.
