Liv Vanserra had always been "Eris' twin". Never her own twin. Forced to do what her father and brother asked of her. She only fully allowed herself to become the ruthless killing machene known to most as Siren, after what had happened to Mor, who had been her only ally in the Autumn Court. And eventually, she began to enjoy it. But when Mor comes back to get revenge on Eris for what he did to her, Liv must make a choice - live a life where she can escape the horrors of her past by not making her own choices, or finally stand up for herself.
