Shibari, the ancient art of erotic restraintaIts finely knotted ropes are a turn-on, a sexual experienceaand, for some, an absolute necessity. At a San Francisco sex club called Pinnacle, Ava Gregory seeks something she cannot quite describe. But of one thing she is certain: the moments when she feels her most beautiful and complete are when she is tightly restrained in the Shibari ropes. At Pinnacle, she's paired with a master: Desmond Hale, who thrives on control. But something surprising happens when Desmond binds Ava's willing body and takes her to the edge of ecstasy. And now the two are taking their relationship out of the shadows of the club, sharing secrets unleashed and bodies unbound.
