Light Harvesters

There are three bold new ways to be alive in 2089, but Hal's damaged brain implant has sidelined him in our wireless society. Some have converted themselves to software, redefining Human. Millions more escape climate chaos by living splendid alternate lives in VR. And a controversial few are digitally immortal, inhabiting advanced synthetic bodies. Then Gracie, a striking woman possessing all the world's knowledge, but no identity, barges into Hal's life. Smitten, he takes her in---and pays a terrible price.
Scanned into living software, Hal and Gracie pursue each other in sun-scorched L.A., and through a lawless virtual realm. There, Gracie's hidden link to A.I. Super-Intelligences darkens the mystery of her origin and purpose, branding her an existential threat.
She is powerful, but neither Hal nor Gracie knows if she is here to help us survive the sixth mass extinction, or destroy us. Humanity is at stake then, when the two confront each other and Hal faces a wrenching decision. No one could have foreseen the consequences.
