Rate this book
Meteors triggers unexplained events that threaten the human race. A team of scientists races to solve the mystery, but can they put together the clues in time?

Earth

The United States faces an unprecedented disaster as meteors strike across North America. However, the damage from the initial impact will be minor compared to what follows. Simon Stillwell and Alex Ramirez lead the team of scientists investigating the craters and the strange environmental changes around them. But while a skeptical administration seems more concerned with how this affects their poll numbers, something has awakened deep within the craters, and it knows exactly what it wants.

The International Space Station

A rogue fragment from one of the meteors hits the International Space Station. Now, the ISS crew finds themselves in a battle to stop an intruder threatening to infiltrate the station. As systems fail and trust is broken, it’s a race against time against an enemy that adapts to every challenge. Cut off from the surface, the crew must put aside their differences and work together if they want a chance at survival.

Terrestrial is an epic thriller featuring authentic characters who must overcome extraordinary challenges as an invasive species threatens to alter the planet forever.

Great read, excerpt from my review at TheBoronHeist:
"McGinnis reminds us that life is precious, that human beings are animals who are a part of this world, and that we can grow to become better. As a reminder, the title of this book about extraterrestrial invasion of the Earth is the inversion of that concept. Terrestrial: this is a book about the human animal, its resilience, and ultimately, the power of sacrifice for the greater good. In some ways, McGinnis has come a long way from his punk rock roots in Carolina to his work as a writer in Texas. In others, his humanism, invested in a nascent anti-anthropocentrism, is still pretty damn punk rock."

One day meteors strike across North America and scientists Simon Stillwell and Alex Ramirez are tasked to find out what causes the changes in the environment. At the same time a fragment also hits the ISS and puts the crew in great danger.
No Xavier Greene this time but an alien invasion of some kind. I kept turning the pages to find out what the 'aliens' wanted and how humankind would respond. Another great story by Ryan McGinnis.
I received an ARC from the author.
