When Dr. Olivia Landon receives this anonymous e-mail shortly after broadcasting her controversial plan to save the condors, everyone thinks it’s a crank threat except Dr. Landon’s daughter Ashley. She’s sure it’s the handiwork of Morgan Rogers, self-proclaimed anarchist and computer geek. 

Suspicions mount when the death threat almost becomes a reality, and Morgan is the only witness. Is he innocent or guilty? Journey into the maze of Morgan’s cyberworld and find out!
