Earthfall, 1

The battle for mankind is about to begin in this riveting tale of Earth's invasion, "a fast-moving story with nail-biting tension” (SLJ) from the author of the H.I.V.E. series.
Sam awakens to see strange vessels gathered in the skies around London. As he stares up, people stream past, walking silently toward the enormous ships, which emit a persistent noise. Only Sam seems immune to the signal. Six months later, he is absolutely alone.
Or so he thinks. Because after he emerges from his underground bunker and is wounded by a flying drone, a hail of machine-gun fire ultimately reveals two very important truths: One, Sam is not, in fact, alone. And two, the drone injury should have killed him—but it didn't.
With his home planet feeling alien and the future unstable and unclear, Sam must navigate a new world in this gripping adventure.
"A vivid page-turner from its opening scene, this fast-paced, action-adventure sci-fi blends the present-day science of nanotechnology, the fantastic concept of distributed consciousness, and the mystery of secret societies to create an edge-of-your-seat read” (BCCB).
