Not all limits can be negotiated.

The Edge is reaching a major milestone. After ten years in business together, Doms Joe Dexter and Heath Anders are planning a celebration and new beginnings. But even the best-laid plans can be thrown off course.

When Olly, Joe's beloved sub, gets caught up in a hostage situation involving Special Forces soldiers, PTSD and blood diamonds, a party is the last thing on Joe's mind. He hates the lack of control, and the thought of losing Olly takes him close to the edge.

Joe is not the only one reassessing his priorities. Olly needs Joe's strength more than ever. He feels safe only in Joe's arms or in his bondage.

Can Joe and Olly find sanctuary in each other or will their latest adventure drive them apart?
