Unwritten: Apocalypse # 10 (Vertigo Comics 2014)

In the first chapter of the final Unwritten story art, Annals of Comparative Literature, Pullman has the maanim, and the end is as nigh as it's ever going to get.
But even magic trumpets have rules, and this one has a homing instinct and there's only one place in all the worlds of fiction where it can do its apocalyptic thing.
Which just happens to be the one place Tom is afraid to go.
