Perseverance: Xenophobia Series - Book 3

by Andreas Karpf

A desperate chase to recover a stolen alien archive…a species focused on exterminating all others…can one ship prevent them from becoming truly unstoppable? “Perseverance” – Sequel to “Prelude to Extinction” and “Latent Flaw”

The room went silent. Jack looked directly at Kurt, but his friend avoided eye contact. His eyes moved to Nadya before following her gaze to Sarah, who stared blankly into the room. He wanted to reassure them – to remind them that they had succeeded. They saved Earth from the remnants of the enemy fleet. But it felt like a lie. The weight of failure sat on him, forcing him to confront the fact that all they did was postpone the threat. His mind locked onto a single it would take just under three hundred years for the enemy transmission with the knowledge stolen from Alpha to reach their home world. Another three centuries after that, a new, stronger fleet would return to Earth in force.

As they reach the threshold of the enemy star system, evidence emerges that everything may not be as it appears. The enemy defies understanding. Fear overrides logic at every turn. And the temptation to succumb to an alien technology – even if it’s the only way to protect Earth – seems irresistible. Coming face-to-face with their enemy, they are confronted with a single, more potent do they even deserve to survive?

About the author

Andreas Karpf is an experimental physicist with a life-long interest in the space program. He enjoys a good space adventure, but lives for the hard sci-fi novel set in a plausible future that doesn't get weighed down by too much technology - a story that takes him for a ride and dream about what may lie ahead for humanity.

As an undergraduate, he earned a degree in Physics and Astronomy, and minored in English. This led him to begin his career as the assistant editor for a physics magazine. He moved into software development, designing business applications. His love of science, though drew him back into Physics where he earned his doctorate and has pursued a research career. Andreas' work focuses on designing new spectroscopic techniques to detect trace gases in the atmosphere. His interests are varied and include art and Taekwondo (where he's a 4th degree black belt). Through his different positions his love of writing has persisted, leading to his debut novel, "Prelude to Extinction." Here he's combined his scientific background with his deep belief in keeping his audience both engaged and entertained. It is his desire to keep his readers thinking and involved in the adventure that drives his writing.
