Once a mercenary, later an assassin, and now living a different life, Dell has bone-marrow-deep loyalty and protective instincts that know no bounds when it comes to his wife, Dolly, a former battle-field nurse, and their close-knit group of Dolly's friends and Dell's allies. When Dolly receives a thinly veiled threat, Dell reverts to his old ways to untangle the background of a prominent local figure, George Byron Benton, whose actions have awakened Dell's obsessive need for security. This target combines the deadly patience of a gila monster and a complex agenda-including a public life that's all elaborate disguise. To penetrate Benton's dense facade, Dell methodically works his way through the only reliable source of news in the area-a blog called Undercurrents. If he manages to track Benton down, Dell will have to decide how far he is willing to go to recapture the sense of safety that Benton has stolen.

With Andrew Vachss's trademark razor-sharp dialogue and inimitable prose style, SignWave-the third entry in the Aftershock series-is guaranteed to reverberate powerfully long after it has been read.
