A forensic thriller with a strong science fictional element, Priest's fourth novel provides suspenseful, intelligent entertainment. On the same day, at the same time, that a man with a gun committed mass murder in Kingston City, Texas, another armed man did the same in the seaside resort town of Bulverton, England. FBI agent Teresa Simons, 43, lost her husband in Kingston City. Now she's visiting Bulverton to determine if the slayings were more than coincidence. Teresa's training included the virtual reality scenarios of ExEx (Extreme Experience), which reconstructs violent events and requires participants to get shot over and over until they learn the right way to fight back. The FBI uses ExEx for training; companies market it for entertainment. Teresa uses ExEx facilities in Bulverton to seek parallels between the two murder sprees. But the GunHo Corporation has a major ExEx investment in the Bulverton incident, and wants to thwart Teresa. Could ExEx's feedback loops have altered time and reality, affecting or even creating the paired killings? Teresa's discoveries horrify her, but propel her into action. She endures a barrage of carnage to find her way back to her love.
