Green Man Blues first appeared in Midsummer Mischief at Caynham Castle, a multi-author, shared world series that takes place in a fictional castle and town in England near the Welsh border. Cassidy and Kell take a vacation to the castle their friends have told them about and end up with more excitement than they bargained for! You can find the other four novellas from the previous seasonal Caynham Castle books in the Castle Magic collection, featuring a trip by Teag and Anthony as well as three stories with main characters from my Morgan Brice books.
