Ever since the chilling tragedy that shattered her world, Kennedy has been trying to keep her brother, Elliot’s, work alive. She sneaks back to her old house (the one her uncle and now guardian Joe is intent on selling) and takes the readings from Elliot’s radio telescope, continuing his search for messages from extraterrestrial beings. But she isn’t the expert that Elliot was, and when she gets a strange reading–a negative frequency that shouldn’t exist–she has to turn to the Internet message boards to ask for advice on how to interpret the results. The consensus is that there must be something wrong with the telescope or the computer program. The frequency cannot exist. But one other user has somehow detected the same pattern of negative frequencies. Nolan has been searching for his older brother ever since he mysteriously disappeared. Although his parents have turned their house into a call center to search for missing children, Nolan is convinced that the explanation for Liam’s disappearance is not so simple. After all, Nolan had a strange premonition the night before that Liam would disappear. And there was that night when Nolan had the high fever that he was so sure he saw Liam in the living room–like he was trying to communicate with Nolan from another dimension. That was when Nolan got the EMF meter and started taking readings in the woods where Liam disappeared. When his path crosses with Kennedy, they realize that the two tragedies that took their brothers might be connected, and that the frequency they’ve discovered might hold the key to solving both of the mysteries.
I would classify this book as a truly character-driven thriller. While the tantalizing mysteries thread through the story, it is the emotional plot of these two teens finding one another and helping each other process the tragedies that truly drives the book forward and makes it impossible to put down. It is a masterful piece of writing that will appeal to fans of thrillers, mysteries, and even realistic fiction. (The sci-fi elements actually turn out to be very light.) Highly recommend it! The audiobook is very good, as well.
