Brilliant cryptologist Dr. Sarah Tu races against time to block the most dangerous Internet malware ever created, a botnet called QUALNTO. While Sarah is closed off in her computer lab, her sister, Hanna, is brutally attacked and left in a coma. As Sarah reels with guilt over not being there for her sister, a web of deception closes in, threatening her and everyone she loves.
Hanna’s condition is misleading. In her coma state, she is able to build a psychic bridge with FBI Special Agent Jason McNeil. Her cryptic messages plague Jason to keep Sarah safe.
Tough and street-smart Jason McNeil doesn’t believe in visions or telepathic messages, and he fights the voice inside his head. His first impression of Dr. Sarah Tu is another stiletto wearing ice-dragon on the war path - until he witnesses her façade crumble after seeing her sister’s bloody, tortured body. Jason’s protective instinct kicks in. He falls for Sarah - hard.
When an extremely dangerous arms dealer and cybercriminal discovers that Sarah blocked his botnet, he kidnaps Sarah. Placed in an impossible position, will she destroy the botnet to protect national security or release it to save the man she loves?
