The Waning by Christina Bergling

Beatrix woke up in a small metal cage, a persistent dripping sound her only company.

Lost in the darkness. Reeling to remember. She had been leaving work to celebrate her promotion, a promotion that was the culmination of her entire ruthless, driven career; a promotion that would cement her status with her marketing firm enough for her to take her relationship with her girlfriend out of the lesbian closet. Beatrix had finally made it.

And then she was here, disoriented and petrified in a black she could not define.Yet the reality of her Master may be even more terrifying than the crushing darkness and enveloping isolation. He appears as an ominous shadow in the doorway of her cell, and he never speaks to her. Instead, he teaches her the language of pain and torture, of submission and obedience, of domination and possession

With each passing day, the fight and hope in Beatrix begins to shrivel and wane. With each savage beating, her survivalist instincts rise up to overwhelm the person she was. With each dehumanizing condition, she begins to forget who she was and the life from which she was ripped.

Can Beatrix ward off the psychological breakdown of her Master? Can she resist the temptation to survive and thrive through submission? Either Beatrix will succeed at surviving and escaping the torments of her Master or her Master will succeed at breaking her completely and reforming her into his design for a human possession.
