Johnno is a Royal Marine and a member of Britain's elite Special Boat Service (Britain's equivalent to the US Navy SEALs). He's passed three of the toughest training courses that the British military have to offer. He's fought in conflicts all over the world. Now, he's about to face his biggest challenge. A retired Royal Navy Admiral has asked him for a favor: bring his wayward daughter Emily home. The only problem? She's working in North Korea. Emily has lived to spite her father for her entire adult life and she's not about to stop now. With a renewed crisis building on the Demilitarized Zone that could erupt into war, Johnno must enter a closed, hostile nation posing as a rugby coach to North Korea's new-and hapless-rugby sevens team. While leading their coaching clinics, he must find Emily and convince her to return home. All the while, Emily finds herself entangled in a dangerous situation that could end up getting both her and Johnno killed. And leaving North Korea might be the final spark to set off the next Korean War. Since 1953, there have been over 750 acts of violence at the Korean DMZ. Now Johnno, in trying to bring Emily back to England, must try and avoid being part of the 751st.
