It's actually quite fabulous, since most books just keep losing numbers until they hit cancellation or stabilize and level off. Upticks that reverse direction into a gain are rare, and are usually due to some event tie-in or anniversary numbering, so this is pretty amazing, cause I don't think it had either. If Invaders can level off at 22K, and this early, that is well above the cancellation line, and it could have a LONG run. It's selling above plenty of other books, at least the print edition.
