Publisher's Synopsis
78,954 alien devices appear just outside Pluto orbit, with a projected trajectory that ends at Earth...and the data shows they're identical to the Gizmo war machine that destroyed ten Earth cities before it was captured and confined.... For four generations Bess Fielding and her family have led the battle to control the destructive Gizmo device that also allowed for the development of Netwalk, a digital virtual networking and communication system that allows personalities to be uploaded at death. Bess, her mother Melanie, and her Netwalker great-grandmother Sarah have suspected Gizmo's alien origin for years. But when a fleet of Gizmo devices arrives at the Solar System, their focus on defending against this invasion is disrupted by disclosures of dark secrets from Sarah's past. These revelations provoke a dangerous breakdown in Bess's grandmother Diana, turning her into a Gizmo collaborator. Bess and her family must unite to save Diana and lead the fight to protect Earth--but who is trustworthy? Who is a betrayer? Who gets sacrificed to stop the invading fleet? Bess, Melanie, and Sarah are in a race against time and face tough choices...that will impact those they love.
