During the latter period of writing, Joe Dever and publisher Red Fox were at odds, and Red Fox ceased publishing the Lone Wolf series after book 28, "The Hunger of Sejanoz", citing lack of interest in the interactive gaming genre, despite hundreds of requests for the reprinting of several Lone Wolf books that had gone out of print. This left the series unfinished, as Dever had 4 other books planned. He first did plan on releasing these books in some form after completing his collaboration on the new Lone Wolf RPG.
