Gnosis

Psychics, government conspiracies, and dangerous criminals swirl like a summer storm around 17yo parkour enthusiast Samantha Black. When a series of crushing headaches lands Sam in the hospital, she wakes to an imaginary voice in her head: Alexander, an adorable ten-year-old who claims to be a telepath. The doctors think Sam's brain was damaged after a stroke, but they're wrong. Alexander isn't imaginary. He's a sentient virus, and the government knows about him. After all, they created him.
