Reyna is determined to protect her niece from the brutal world she once endured, even if it means killing the dangerously alluring man chosen as her fiancé. Spider, meant to wed the innocent Lili, finds himself obsessively drawn to Reyna instead—fiery, fearless, and completely offlimits. As their forbidden attraction grows, so does the risk of betrayal, bloodshed, and a love that could destroy them both.
