If This Book Exists, You're in the Wrong Universe: A John, Dave, and Amy Novel (John Dies at the End 4)

Jason Pargin

A large black book is tilted in the centre of a bright lime-green field, with glossy black drips extending from it and a skull below. The title appears in four stacked lines of tall, condensed, pale-grey uppercase sans-serif lettering across the book's front; the author's name, JASON PARGIN, appears in a separate large line beneath it.
