American Chillers
American Chillers and its predecessor series Michigan Chillers are a series of horror novels for children written by author Christopher Wright under the pen name of Johnathan Rand. The original series began in February 2000, with each book taking place in major cities and places in the author's home state of Michigan. Its spinoff American Chillers was launched in December 2001 with a national focus, set to cover all fifty states and in the same continuity as the parent series, with its first book introducing a new character who teamed up with the protagonists of Michigan Chillers #1 and 9, while also including cameos by the main characters from five other books in the parent series. It, and every book since, concludes with the main character meeting a kid from another state, who had their own scary adventure and serves as the main character in the next book. As of the 2023 release of book 45, only five states remain to be covered: Kansas, Maryland, Louisiana, New Mexico and Hawaii. List of Michigan Chillers books
