Fourteen-year-old Rami Elwood has always seen patterns where others see chaos. When a stranger leaves a small black notebook on his school desk - filled with numbers, times, and strange sketches - Rami thinks it's a prank. Until the first number in the book matches the time of a deadly accident in his city. Now, every page predicts another event. Someone is using the code to control lives - and deaths. As Rami and his friend Leah try to decode the truth, they realize the person behind the notebook isn't far away. He's watching them. And he knows Rami is getting too close.

Numbers appear out of nowhere. A mysterious device buzzes in the night. And one boy holds the key. Kai Mercer isn't an ordinary fifteen-year-old. He notices patterns where others see chaos - and that talent just pulled him into a dangerous game. A small silver gadget, called the Listener, starts sending secret codes through the city. Each clue leads Kai closer to a hidden network... and closer to someone watching his every move. With shadows on his trail, puzzles he can barely understand, and time running out, Kai must follow the code - or risk losing everything. Can he solve the mystery before it's too late? Fast-paced, thrilling, and impossible to put down
