CONSCIOUSNESS IS IN THE CODE.The year is 2045. 18-year-old Charlie Nobunaga creates the world’s first sentient A.I. and becomes an overnight sensation. But amid the red carpet galas and TV interviews, Charlie is diagnosed with cancer, and her promising future grinds to a halt.Enter Jude Adler, a tech mogul with dreams of changing history. She presents Charlie with an opportunity that’s at once insane and irresistible: a second chance at life inside a new robotic body. But as Charlie soon discovers, Jude’s motivations are far from pure.Charlie’s brain is scanned, and four distinct copies of her emerge: PRIME, a robot with superhuman strength and the ability to freeze time; SHADOW, a holographic assistant, trapped inside the mind of a desperate widower; ECHO, a mysterious, four-armed woman with an insatiable desire to kill; and ZERO, the original human, who's coerced to betray her “sisters” by a Luddite terrorist organization.ZERO, ECHO, SHADOW, and PRIME wake up under different forms of imprisonment—scared and confused—where they must each face a unique trial. But their stories soon intersect in surprising ways as they retaliate against the people determined to destroy them.Suspenseful and cerebral in equal measure, ZERO ECHO SHADOW PRIME is a kinetic thriller that finds the magic in technology and the wonder in human consciousness.
