In the late ’80s, a historical romance pro named Francine Rivers became a Christian and decided to combine her creative interests with her newfound faith. The result is “Redeeming Love,” a runaway hit that repackaged a few verses from the Book of Hosea into a historical romance complete with trauma, betrayal, sex and more trauma. Tyler is joined by novelist Liz Riggs (who is, full disclosure, also his wife) to break down the bodice-ripping, slut-shaming epic.
