Submerged

"Deep under a Nevada lake is a mystery of historic proportions and personal pain... As senior project manager for his father's construction firm, Perry Sachs has helped build top-secret military installations around the world. Now he learns a secret beyond his imagination - one on which his father's life depends. Forty years before, Henry Sachs and a small group of scientists had studied a mysterious underground base not built by the U.S. government - nor any other country, as far as the experts could tell. Concerned by the unexplainable complex on American soil, authorities flooded the site to prevent its creators from ever returning. Now, Henry and members of his team are falling, one by one, to a strange, deadly illness. When Perry hears his father whisper the name, "Lake Lloyd," he and his team begin a desparate search - for the exact location of Henry's secret mission, for the cause and cure of his condition, and for answers to the decades-old questions Henry has kept hidden inside."--
