Dreamwatch, a site where ordinary people share paranormal experiences, began as a hobby. It was supposed to be fun-until premonitions from around the world predict the same deadly attack. The last time reluctant psychic Kate Kasabian revealed a prediction, people were hurt. With thousands of lives at risk, she has no choice but to badger her FBI brother to investigate. He refuses to help. When she sets off to prove her suspicions, he thinks he's heard the last of her supernatural silliness-until the legendary Matt Chase from Counterterrorism alerts agents to a credible threat. Every detail of Chase's briefing is identical to Kate's warnings. Tracking clues from Prague to New England, Kate trusts dreams and premonitions, while Chase relies on intelligence and technology-but will it be enough to stop the U.S. plot.
