Born deaf in 1968 and raised to read the world through mouths instead of ears, Olivia Reyes spends two decades hiding in plain sight as an NSA lip-reading analyst — until a state dinner at the White House puts her eleven feet from a terror cell, and her silence stops being a place to hide and becomes a place to hunt from. Exposed, tailed, and ambushed by a network she can't yet see the shape of, Olivia finds the one place she still feels safe — a relationship with a charming stranger who signs fluently and asks just slightly too many questions. As the walls close in from every direction, Olivia has to decide whether the man she's falling for is the one person outside the agency she can trust, or the most dangerous read of her career.
