The Preserve — Steve Anderson

A WWII vet finds himself trapped inside a sinister military experiment in this historical thriller based on true events and sequel to Under False Flags.

Hawaii, 1948. In World War II, Wendell Lett was considered a hero before he became a deserter. Now he's looking for a cure for his severe combat trauma, and The Preserve seems to be his salvation. Run by military intelligence, the secretive training camp promises relief from the terrors in his mind. Together with tough-minded Hawaiian Kanani Alana, who's also looking for a new start at The Preserve, Lett begins to feel hopeful. 
But soon Lett discovers the chilling, true purpose of his treatment. The Preserve intends to rebuild him into a cold-blooded assassin -- whether he's willing to cooperate or not. His only hope is Alana's dangerous escape plan. But even if it succeeds, he'll still have to survive a merciless manhunt through the harsh wilderness of the Big Island.
