"Mapmaker expertly brings the paranoid thriller into the age of surveillance, and the result is both moving and chilling." —D.B. Weiss, co-creator, writer, and producer of Game of Thrones When Tanya Barrett takes an internship at MapOut, she expects emotional landmines. Her father cofounded the digital mapping company, and he died for it—on a cartographic expedition. Her father's business partner welcomes her with open arms, as does his son, Connor, an old childhood friend. To Tanya's surprise being with Connor turns out to be the only thing that makes her feel happy. But when the two of them accidentally stumble across a deadly secret, Connor disappears. Alone again—and on the run—Tanya must rely on her wits and innate gifts to find out what happened to him and to evade MapOut. In the world their fathers helped create, no one stays lost for long.
