Extraordinary! A deserving Pulitzer Prize winner.
It's a lot, and it's extremely heavy (literally and figuratively), but it's incredibly well done and worthwhile.
I concede I'm partial to the medium, not just graphic novels, but non-fiction graphic novels, and I'm guessing I'm not alone thinking back to Thi Bui's The Best We Could Do or (and this is little further afield, but) George Takei's They Called Us Enemy. Sure, you can drift even further and analogize to Marjane Satrapi's sublime Persepolis or Art Spiegelman's Maus, or, I dunno, in terms of self-discovery (and healing) maybe even Maia Kobabe's brilliant Gender Queer, ... or, I dunno, Alison Bechdel's Fun Home or even Kate Beaton's Ducks, ... but at some point, it's worth acknowledging that that non-fiction graphic novels (or serial art) represent a special place in an ever expanding, rich, and far-too-often underappreciated format (or art form).
At some level remarkable people, who have led remarkable lives, do remarkable things ... and, to me, that's very much in play here.
I'm glad that the Pulitzer Prize committee was open to, and recognized both the genius and the appeal, of Hulls' work. I understand, from a news interview, that Hulls considers herself to have gone one and done with regard to books of this type, but I'm very much curious to see what she does next.
I can't recommend this enough!
