Anthony Monday (series)
Anthony Monday is a fictional 14-year-old American boy featured in a series of four children's gothic horror novels by John Bellairs that were published from 1978 to 1992. Anthony and his friends generally overcome evil forces bent on ending the world. Alternatively, Anthony Monday is the book series, as in ISFDB. Brad Strickland, who has completed Bellairs' works posthumously and written new novels based on his characters, has noted that Anthony Monday was disliked by those in charge of publishing and any book ideas with Anthony as the character were rejected. This is why there has not been an Anthony Monday book since John Bellairs died. Novels in the Anthony Monday series
