Diamondback Cave

Imogene Vandergrift is behind bars but is willing to do almost anything to get out and reclaim a fortune in diamonds she has stashed away. Jack Mackey, a television reality-adventure star, has no interest in her, especially after what she did to his son Wesley. For years she posed as Wesley's mother, and Jack promised him she would stay locked up. That promise stops holding once Alex Harris, Amanda's future stepfather, vanishes without a trace.

Wesley and Amanda, his closest friend, decide to search for Alex themselves. Their quiet investigation points them to Diamondback Cave, a dark opening in the earth named for the rattlesnakes that crowd its entrance. The diamonds are hidden deep inside, but the cave holds other threats as well, including henchmen who may be working for Imogene or against her. As the attacks escalate, Wesley and his loved ones must hold together, and Amanda must find Alex before he can become part of her family.
