If you remember, Ford MacDougal (Mac) first appeared in The Maze, at Quantico with Sherlock. Now Mac is flat of his back at Bethesda, seriously wounded in a terrorist car bombing when he dreams that his sister, Jilly, a medical researcher, drives her Porsche off an Oregon cliff. Only thing is, Mac feels like he's with her.
When Mac arrives in Oregon to find out what's going on, Jilly comes out of her coma, only to disappear a few hours later without a trace. In searching for her, Mac hears a different story from everyone he encounters, even from the local sheriff. And then there is Laura...a woman who fascinates him, a woman who could kill him if he trusts her.
When a local old man ismurdered, Mac doesn't at first suspect that the case connects to his sister's disappearance. FBI agents Savich and Sherlock (last seen in The Target) join Mac to ride shotgun. Not knowing whom to trust and whom to suspect, they must escape relentless pursuers before unearthing the tentacles of evil undermining The Edge.
This is #4 in FBI series.
