Until the World Falls Down by Jordan Lynde

Her freedom or her heart… in forty-eight hours, she’ll lose one forever.

When a brutal betrayal leaves twenty-eight-year-old Nell heartbroken, she makes a desperate plea for love—offering anything in exchange. But when her bargain is answered by Enver, a cursed immortal bereft of emotions and memories, she is swept away to his timeless castle and presented with an impossible choice: escape his labyrinth within forty-eight hours or surrender to an eternity as his lover.
Despite the passion that burns hot between them, Nell refuses to become another of Enver’s victims. She vows to face the labyrinth—and his seduction—head-on. But Enver embodies temptation, and every stolen moment with him leaves her craving more.
With every step deeper into the labyrinth, she uncovers not only hidden truths about herself and what she truly desires but also the forgotten secrets of its enigmatic ruler. With every touch, their connection deepens, and Nell begins to see beyond Enver’s shadowed facade, realizing he may not be the monster he claims to be.

Torn between her desire for love and the dangerous being incapable of loving her, Nell must choose between her heart and her freedom—or risk surrendering both to his darkness forever.
