Okay, I talked to the probable publisher last night — John Betancourt from Wildside Press — and he wants a different title.
I think he’s right; The Final Calling was kind of a stopgap I stuck on the project when Tim Powers published a novel using my original title, Last Call. It’s not a very exciting name for the book.
I came up with the obvious The Last Warlock, but other suggestions would be welcome.
There’s no prize involved, and titles aren’t subject to copyright, so if I do use yours you’ll get nothing out of it but my thanks, and the odds are pretty good I’ll wind up using something I came up with myself (maybe inspired by a suggestion here), but still, if you have any clever ideas, I’d like to hear them.
