What the Hell Did I Just Read: A Novel of Cosmic Horror is a 2017 comic horror novel written by Jason Pargin under the pseudonym of David Wong. It is the third book in the series after John Dies at the End and This Book Is Full of Spiders. The novel continues to follow author surrogate David Wong, his best friend John and his girlfriend Amy, who are living in an American Midwest town, the name of which is undisclosed, and which is referred to as "Undisclosed" throughout the book. The town has long been a place from which eldritch creatures enter our world from other realities and dimensions, viewing humans as useful cattle at best and disgusting insects at worst. Dave and John have the ability to see these creatures, invisible to regular humans, after encountering a substance known as the "Soy Sauce" several years ago, as depicted in John Dies at the End. This has led to them becoming semi-experts on dealing with the supernatural among both police and the general populace, over the years gaining fame in certain circles, despite both struggling to maintain financial stability. Synopsis One night, John and Dave are called to investigate a closed room disappearance of a little girl named Maggie Knoll. After questioning her father Ted and following up on the leads, John and Dave quickly establish that the abductor is a supernatural entity that can present itself in different forms, even to people in the same room. As they continue their investigation by questioning Maggie's mother Loretta, Dave's girlfriend Amy is confronted with a doppelgänger of Dave, who leads her to the girl's location under a pond near a collapsed mining shaft. As the girl is reunited with her parents, she identifies Dave as her kidnapper, but Dave and John manage to convince Ted and Loretta that this is another trick of the supernatural kidnapper. John, Dave and Amy find and trap a small insect-like creature that can disguise itself as any living or inanimate object, inserting retroactive memories of its new form so that it doesn't arouse suspicion. Before they can investigate it, another child goes missing under similar circumstances, whose mother Chastity Payton believes it to be related to BATMANTIS???, a large flying creature spotted and filmed in the area. Police detective Bowman arrives to question David on Maggie Knoll's case and finds the second child unconscious in
