This book is a must read, for any dead space enthusiast. It reveals the origins of the mysterious artifact, that was re-engineered to create the red marker (As seen in dead space1) placed on aegis 7. Not only does it cover that unanswered qualm, it even goes as far as to shed some insight into the origins of that infamous cult "unitology". Whether you're a fan of the franchise or are looking for something worth reading to pass the time; I would definately recommend this book to you.
