Signals We Don’t Speak Under the Sky of Seoul – Book 3 By A.H. Mercer The silence is no longer safe. In this gripping third installment, Chris Nolan searches for the only person who ever truly saw him: Hye-jin. After her mysterious disappearance into a surveillance system gone rogue, Chris is thrust into a darker world where voices are hijacked, memories are coded, and trust is a liability. As encrypted broadcasts and ghost signals start surfacing across Seoul, Chris uncovers that Hye-jin hasn’t vanished—she’s become part of the very machine they tried to shut down. But to reach her, he’ll have to break through REVERB: a program designed to manipulate reality itself. Hunted by the mysterious figure known only as Lazar and betrayed by systems designed to forget, Chris must follow her trail through digital ruins, underground servers, and memories she never meant to leave behind. But not all signals are meant to be decoded. And not every love survives the silence. Book 3 is where trust fractures, voices return, and the real war begins.
