Gwenpool, The Unbelievable Vol. 4

Book excerpt: Collects The Unbelievable Gwenpool #16-20. Gwen Poole is everyone's favorite character from the "real" world! And her super-power is Official Handbook-level knowledge of top-secret comic-book facts! But the longer she's in the Marvel Universe, and not reading about it from the outside, the more her powers run out...or do they? Maybe a trip back to her world might help - but if that happens, will she be able to return to the MU? And at what cost? Plus: Gwenpool is no stranger to trouble, but she'll brand herself a menace when she blurts out a certain somebody's secret identity! You'd have thought by now that she'd know what comes with great power. How can she fix her self-induced continuity drama? And, er, who's that evil-looking version of Gwen?
