No Towers holds No. 1 spot: ICv2.com notes that Art Spiegelman's In the Shadow of No Towers has topped BookScan's list of graphic novels sold in bookstores for the third straight week. Marjane Satrapi's Persepolis holds the No. 2 spot (it's not clear from the article whether that's her first or second book; I presume it's the sequel). Manga hold 47 of the Top 50 BookScan positions.
