"C.M. AMOS grew up in the '60s and '70s before Asperger's and Autism became widely known, so like many, Amos went undiagnosed until reaching adulthood. After the World Trade Center attacks in 2001, a deeply rooted need for understanding led to countless hours dedicated to recording and journaling about historical events and their connections to prophecy. ""The Four Horsemen"" is Amos's first book in the ""Clashes of the Caliphate"" series and a direct result of those hours of study."
