The Pathfinder Initiative, Shadow Apocalypse, Book One

In 2065, terrorists seized control of a nuclear weapons instillation in Northern Russia and in one act of fanaticism, they sealed the fate of mankind.
Leaving behind their irradiated homelands, the survivors of the Earth head out into the night and start the hugely ambitious and dangerous task of building a permanent colony on Mars.
The year is now 2102 and against the odds, the Sanctuary colony and its inhabitants have thrived and have started to explore other worlds.
Hundreds of light years away on Ashen 2, a team of scientists make an unprecedented breakthrough that could herald a new golden era for mankind, but instead unleashes a new and unpredictable terror.
When communication with Ashen 2 is lost, a mission to investigate is quickly launched.
Amongst the team is Robert Hewson, an experimental physicist responsible for the ongoing terraforming of Mars.
Hewson soon finds himself being carried along in a whirlwind, as he and the rescue team engage a faceless enemy across space and time.
Something has been watching them from beyond the veil and the fight for survival has just begun.
