Liberty's Run: Book One - The Liberty Schoenhauer

As if zombies crowding the streets wasn't weird enough, librarian-turned-sniper, Liberty Schonhauer, finds that some darn aliens created the virus that decimated Earth. And now, those very same aliens are about to abduct a boy, Colin, who may hold the key to a vaccine. Not that Liberty would've let them have any child, under any circumstances.

Spiriting the boy away, Liberty is quickly joined by the badass Uncle Danny [no relation to them]. The two get the boy to a Fleet of ships, off the coast of Southern California.

Liberty and Uncle Danny, swiftly becoming best friends, start to work for the Rear Admiral of the Fleet.

First to resupply the Fleet with prescription drugs, and then to rescue other survivors. But the aliens have let loose a new complication: predatory alien-birds that are almost as tall as a person, and hunt anything that moves fast.

However, the creatures may not be just vicious fowl.

These new aliens may have an intelligence that rivals our own. Thinking on their feet, the two focus on getting home to Colin; around whom a new family is quietly forming.

Despite all the zombies and aliens, Liberty's Run strives to take a realistic approach to dealing with an environment like this.
