'Time to Reap' by Jim Trombetta

The Eternal Spirit orders Malzor to journey back in time, on a mission to reach the first wave of alien warriors that tried to invade Earth. While Mana uses Morthren technology to change Malzor’s appearance to that of an F.B.I. Agent named McGruder, the alien scientists take advantage of a planetary alignment in their bid to create a time-space portal. When the aliens drain the city’s power supply and cause a mass blackout, Harrison, Suzanne and Kincaid track the source of the disruption to an abandoned fun fair, where the aliens have created a gateway to the past inside the Hall of Mirrors. As a gunfight breaks out, Malzor leaps through the portal; Harrison and Kincaid follow, and find themselves transported to 7th September 1953, in Harrison’s home town five days after the invasion ended. Knowing that the only way to return to the present is by finding Malzor, Harrison resolves to elicit Doctor Forrester’s help, only to learn that the scientist is currently out of town. After Harrison meets his younger self and gives him some useful words of advice for his future, he and Kincaid team-up with local reporter Miranda Watson; together they try to warn General Mann, the man in charge of the military’s defence during the incursion, but the soldier refuses to listen and has them arrested. Meanwhile, Malzor kills the real F.B.I. Agent McGruder and takes his place; using mind control the alien then takes over General Mann and uses him to gain access to a crashed alien warship. Malzor intends to inoculate the surviving crew against Earth's bacteria – unless Harrison and Kincaid can get free and stop him, he will change the course of history, and the aliens will be victorious…
