When the world comes under threat, an elite international team is called in, designed to handle the highest of stakes and led by former Army Ranger Grant Valor.

In MAXIMUM PERIL (Book #5), when major dams fall under terrorist control, it’s up to Grant Valor and his team to dive deep into hostile waters and dark tunnels to avert global catastrophe.
