It begins at night. People vanish from parks and city streets. Then in broad daylight, they’re dragged screaming into the woods, into the water, into the sky. People take refuge in their homes, but still the invisible creatures come, ripping people away from their horrorstruck loved ones. Spouses. Parents. Children. Nowhere is safe and no defense can stop them. Because nothing can save you from what you can’t see.

High school teacher John Calhoun loses his son the first night. A day later, they take his wife. For two months, he and his thirteen-year-old daughter manage to survive, but in the end, she is abducted too. In John’s darkest moment, he meets a motley group of survivors who have a secret: a near-fatal car accident has given one of them the ability to detect what normal human eyesight cannot.

The survivors believe they can replicate the brain injury that will enable them to see the creatures. To discover how they’re invading our world. To fight them. Desperate to save his family, John volunteers. And after the veil of invisibility is lifted, he and his new friends will risk everything to achieve the impossible: enter an alien world and bring their loved ones back.
