Synopsis

Signal Fire: A Novel

Bestselling author Melissa F. Miller returns with a fast-paced, morally tangled, and deeply human thriller with emotional depth and razor-sharp twists.

Married covert operatives Sasha McCandless-Connelly and Leo Connelly are navigating their first joint mission for the Lighthouse, a private intelligence agency that steps in when governments can't. Their assignment: uncover the truth about rising literary star Caleb Rye and his eerily prophetic thriller novels.

At Foggy Bottom Preparatory School—a haven for the children of diplomats and spies—Rye teaches English by day and writes by night. His last two books predicted terrorist attacks. Coincidence? Or is his fiction rooted in dangerous fact?

The mission takes on urgent new stakes when Rye announces his latest book, centered on a political assassination. As Sasha and Leo dig into the manuscript and Rye's mysterious rise, they uncover a forty-year-old black operation gone horribly wrong—and a betrayal that points straight back to their new employer.

Signal Fire marks the return of two of Miller's most beloved characters in a gripping, high-stakes thriller that explores the cost of secrecy, the weight of legacy, and the burden of buried truths.
