A female federal agent and Milwaukee PD join forces against domestic terrorists in a timely and explosive thriller. Ex-Marine Force Recon Officer and Milwaukee Police Detective, Declan Tomczyk, is dispatched to investigate the desecration of headstones at Holy Cross Cemetery. What first appears to be the work of vandals becomes something far more alarming. Tomczyk has come upon a trip wire connected to a crude homemade bomb. With it, an anonymous note threatening that "the days of terror have returned" . . . Murder by murder, the promises are being fulfilled. Enlisting the help of FBI Agent Anne Dvorak, Tomczyk is now tracking a series of violent crimes, eerily similar to those that paralyzed the state decades before. With the unlikely assistance of a former pro linebacker and a World War II veteran—each one a surprising conduit between the past and the present—Tomczyk and Dvorak are getting closer to the truth. But who is the ultimate target? And what's the inconceivable endgame for homegrown extremists determined to hold the city hostage? With time running out, and casualties running high, Tomczyk and Dvorak must risk their own lives for the answers.
