The Night Hunter 2

Six years since the A Shau Valley incident, and the Ky Lan is back. Contact has been lost with a secret military facility on the Vietnamese island of Con Son. The final transmission is just a few broken words. They are being hunted.
There have been rumours of this creature for years, with the stories covered up and buried to hide the terrible truth. As the country collapses from within it falls to an elite unit made up of special forces, military specialists, and others to return to the island to rescue any remaining survivors. But first they need the help of the one man has seen the beast and lived to talk about. A man that can get them on and off the island unnoticed by the thing that hunts the living.
Shunned and pushed aside for the last six years, Billy Richards is a shadow of the man he once was. Discharged from the military, he spends more time in the bars drinking himself into a stupor than working as private security operative in Saigon. Tormented by his loss, Billy hunts the creature the only way left open to him, searching for clues and information wherever he can. When he is offered a chance to join the operation, he knows what he must do. For the memories of his platoon he must face the creature once more and destroy it for good.

It is a story of heroic soldiers from both sides fighting for their lives against an unseen horror in the middle of the Vietnam War. A full-length novel by the Michael G. Thomas and Eric Meyer, the bestselling authors of Star Crusades, Heroes of Afghanistan, Devil's Guard and many more.
