In a futuristic shifter-contract world, orphan Ruby spends all savings buying gorgeous white fox Lucien, who grows arrogant and abuses her while flirting with noble Stella. Hurt by his cruel insults after another injury, she decides to swap her shifter at the registry. By chance, she spots Blaise, a fierce war-bred werewolf doomed to bloody fighting pits. She chooses the abandoned wolf over her ungrateful fox, leaving stunned Lucien bitter and regretful, setting up his desperate later pursuit for redemption.
