After surviving an infamous family tragedy, 16-year-old Kennedy Jones has made it her mission to keep her brother's search through the cosmos alive. But then something disturbs the frequency on his radio telescope - a pattern registering where no signal should transmit.  In a neighboring county, 17-year-old Nolan Chandler is determined to find out what really happened to his brother, who disappeared the day after Nolan had an eerie premonition. There hasn't been a single lead for two years, until Nolan picks up an odd signal - a pattern coming from his brother's bedroom. Drawn together by these strange signals - and their family tragedies - Kennedy and Nolan search for the origin of the mysterious frequency. But the more they uncover, the more they believe everything's connected - even their pasts - as it appears the signal is meant for them alone, sharing a message only they can understand.  Is something coming for them? Or is the frequency warning them about something that's already here? ©2019 Megan Miranda (P)2019 Listening Library
