Earthfall: Retribution is the second volume in Mark Walden’s dystopian science fiction series which began in Earthfall.
Months after the events of Earthfall, Sam continues to try to dispel the trance-like state that has gripped the enslaved people of London. He and his friends had thought the gargantuan Voidborn drilling device they disabled was the only one like it in the world. They were wrong. There are hundreds of others scattered around the world, and all of them are almost near the final stages of construction. Sam and his friends team up with a similar resistance team in Tokyo, and they help them disable their own monstrous device. However, Sam has to learn to pick his allies carefully, for when the world is at stake, there are only a few people you can trust. Taking the events of Earthfall to a global scale, this book breaks out all the stops in showing us what is really happening on the one planet we call home.
