Dark Whispers — Karen Sandler

In this dark fantasy with a multicultural cast, a group of scientists face a supernatural horror hundreds of feet underground. Botanist Liz Madison agrees to marry the arrogant genius Ethan Winslow to qualify for residence in BioCave, a marrieds-only experiment deep beneath the stark Western Sonoran Desert. The ghost that Liz encounters is the least of her worries when something far more evil starts picking off the scientists one by one. Liz thinks she can have a life with Ethan beyond Bio-Cave, but first she'll have to survive the malign spirit…and Ethan himself.
