J.A. Kerswell is the author and creator of "The Slasher Movie Book"; a glorified history anthology focused on the slasher sub-genre. The book includes a detailed and comprehensive timeline for the slasher genre and its global releases. Not only are there descriptions for each movie and time period, Kerswell includes theatrical posters and B-movie images. I have to say personally that I love my copy and hold it as a totem to horror! Fans of the slasher genre will get a kick out of what it teaches.
