I believe he also edited Three Parts Dead
by Max Gladstone.
Crediting editors can be a bit tricky sometimes. It's entirely possible, at Tor and Pocket and everywhere else, for a book to be acquired by one editor, edited by another, and maybe re-edited by yet another editor, just because of staff turnovers, editorial realignments, creative differences, and so on.
Case in point: To Reign in Hell
was acquired by John Ordover, who worked closely with me on the original outline, but John had departed for greener pastures by the time I delivered the actual manuscript, which was edited by Ed Schlesinger. Ditto for my second Underworld book.
That sort of thing happens all the time. It's not at all uncommon for a manuscript to pass through two or three editors on its way to publication.
Heck, sometimes it's just a matter of lightening somebody's workload. "Hey, Greg. Sybill is swamped with the Space Vixens
books. Would you mind taking over the vampire romances for the time being?"
