A senior intelligence officer burns an allied deep-cover network. Then he dies.
The last secure records contain an impossible detail: someone was watching him from inside a channel no outsider should have been able to see.
Scott Evers is pulled into an investigation where every supposedly secure system may contain another observer, every agency has something to hide, and looking too closely can expose the very people he is trying to protect. This time, Cynthia refuses to remain outside the strategic fight while other people decide what she is allowed to know.
Someone has crossed the Glass Line. Scott intends to find out who. But when the watchers themselves are being watched, trust becomes the most dangerous vulnerability of all.
Restored. Revised. Relentless.
