When betrayal destroys everything you love, how far would you go for revenge? Ariella Hart had it all—a thriving corporation, a loving family, and what she thought was the perfect man. Until Blake Sterling stole everything from her with a smile and disappeared, leaving her pregnant, penniless, and utterly broken. Desperate and alone, Ariella makes a deal with the devil himself: Grayson Wolfe, Chicago's most ruthless billionaire. The contract is simple—carry her baby to term, hand it over to him, and walk away with enough money to rebuild her shattered life. But nothing is ever simple when it comes to the Wolfe family. What starts as a cold business arrangement ignites into something dangerously real when Grayson's protective instincts and unexpected tenderness begin to heal Ariella's wounded heart. Just when she starts to believe in love again, a shocking revelation threatens to destroy them both: Blake Sterling isn't just the man who ruined her life—he's Grayson's son. Caught between father and son in a web of lies, betrayal, and twisted family secrets, Ariella must decide: Is her growing love for Grayson worth the risk of being used as a pawn in their deadly game? Or will the truth about her contract marriage destroy any chance they have at real happiness? Some wounds cut deeper than others. Some secrets are worth killing for. And some love stories are written in blood.
