Talking to Tim Martin of Aeon Magazine, Alan Moore talked about his intent to finish the grimoire in the manner of British children's annuals of old, The Moon And Serpent Bumper Book Of Magic, co-authored with the late Steve Moore.

Tim writes,

Moore will, he says, be finishing 'The Moon and Serpent' book himself in due time. 'I don't think it's going to be a huge problem that one of the heads of the order is no longer corporeal.'

A 320 page hardcover, the book is intended to be published by Top Shelf and Knockabout and will include art by Kevin O'Neill, Melinda Gebbie, John Coulthart and José Villarrubia.
