For three years, enslaved Brielle has entered Alpha Gideon's room in darkness, wearing Odessa's scent and taking her place in his bed. Gideon knows the deception yet refuses Brielle a name, protection, or freedom, while Odessa threatens her young sister and plans to marry Brielle to a brutal man. Desperate to escape, Brielle volunteers for a soul bond with Evander, Gideon's cursed elder brother, an Alpha heir expected to die within months. What begins as a pact of survival changes when Brielle's wolf calms Evander's dying spirit and her stubborn care gives him a reason to fight. As Gideon uncovers the truth and Odessa tightens her control, Brielle must decide whether she is still someone else's substitute or finally the author of her own fate. This time, she chooses.
