More than thirty thousand years ago, mankind was not alone on the planet Earth. No, it's not science fiction, but reality. Homo sapiens shared the planet with Homo neanderthalis, otherwise known as Neanderthals. Short and stocky, with a pronounced ridge of bone over they eyes and with receding chins, Neanderthals have captured the imagination of people ever since this subset of the human family was discovered. For at least sixty thousand years, Neanderthals competed with Homo sapiens -- us -- for food and living space. It was a competition the Neanderthals didn't win. Eventually, they went extinct.
Or, as we find out in Colin Harvey's fantastic novel, Lightning Days, they might just have left. In the mountains of Afghanistan, British -- sort of -- spy Josh Cassidy leads untrained soldiers into a warren of tunnels searching for the unknown. They found it in the form of hundreds of modern day Neanderthals (Thals) on the run from the gestalt-mind Sauroid race, which is out to extinguish every timeline but their own.
Harvey does a fantastic job of weaving together disparate threads as our world comes under attack from both the Sauroids and the very laws of physics themselves. This is a book that I could not put down. I had to know what happened next.
