Renegade

In Renegade by Ann Voss Peterson, four couples, including former Wisconsin police chief Val Ryker, reunite at a luxury guest ranch in the Wyoming mountains for a unique research study on love that forces them to confront their past traumas. Participants are promised a lavish vacation filled with adventure, but the billionaire behind the study has darker intentions, aiming to explore how they cope with present terror rather than healing from the past. As they navigate therapy sessions and thrilling activities, the couples must face the unsettling question of whether love can truly conquer all in a life-threatening scenario.
