Hell on Earth (novel)

Hell on Earth is the second novel of the novelization series written by Dafydd ab Hugh and Brad Linaweaver.

Book Description
''They were creatures seemingly spawned straight from the pits of Hell—demons, zombies, fire-breathing imps—all too horrifically close to the stuff of nightmare to be real. But they were. And on the inhospitable moons of Mars, Corporal Flynn "Fly" Taggart, Earth's last line of defense against a seemingly inexhaustible supply of alien warriors, beat them back almost single-handedly.''

''But Taggart discovers that the war had barely begun...for while he was fighting them on Mars, the hellish creatures had established a beachhead on Earth itself. Now, with the aid of a fourteen-year-old female computer genius, an unrepentantly Mormon sniper, and the best soldier in this woman's army, Fly Taggart must defeat the invaders—and their treacherous human allies—yet again...''

Plot Summary
The second book opens right as the first ends, with Fly and Arlene stranded on Deimos, in Earth's orbit with the oxygen leaking out of the base. Fly gets the idea to build a shuttle craft to carry them to Earth - a risky, improbable plan, and while they have the parts from "mail tube" unmanned shuttle parts, their experience lies in the fact that Fly once built a car out of spare parts.

Over the next month, the two build their craft, but as the oxygen runs low and they start to hallucinate and run out of food, they fly their shuttle, managing to survive the tri. Eventually, the two land several miles away from Salt Lake City. A several days' walk leads them to the city, and the truth - humanity is an endangered species. SLC is one of the few human resistance strongholds, as the Mormons had a survival plan and years worth of supplies for such an event.

Arlene expresses displeasure over their surroundings, as her brother had converted to Mormonism during his own downward spiral in life. Fly makes things worse when he contacts Marine HQ. As it turns out, world governments turned traitor to the aliens, as did their militaries. Within hours, armed forces from the Marines, FBI, Army, ATF, and IRS (a "revenue collection" armed branch) attack the city.

The President of the Twelve, displeased at Fly and Arlene's failure, offer them a chance to make amends - lead a team into Los Angeles, recover vital information, disable the aliens' shields, and fly the information to a Marine resistance center in Hawaii. With them will be Albert Gallatin, an ex-Marine sniper/converted Mormon, and Jill Lovelace, a fourteen-year-old former computer hacker who lost her parents in the invasion.

The book follows their trip west. On the trip, Arlene falls in love with Albert despite his religion. Jumping a train headed west, the team kills a Spider Mastermind and a Cyberdemon and recover their human hostage - Ken, a young man with numerous computer implants in his body. Reaching LA, they find that the chemical brew that turns corpses into zombies is made by stoners and other drug addicts, those allowed to remain alive by the aliens for turning traitor.

Having determined Ken to be the information they need, they reach the airport. Albert is burned severely by an Imp fireball, but is luckier than Bill Ritch and survives. Albert and Jill remain behind to fly the plane to Hawaii, while Fly and Arlene head to the Disney Building to disable the massive force shield. They succeed, but a gathering of monsters has them trapped. But Arlene has an escape plan...
