Author Brett Herrmann will hold a book discussion and signing for his first fiction novel “Grim Sweeper”. The story follows a high school janitor, who sees himself as more of a private eye investigator. His case solving leads him into a web of deception where he finds out some messes are even too big for him to clean up. Herrmann, a Spring Valley native now residing in Sycamore will make the trip to the library for the event.
