Walt and Emily by Paul DiFilippo
For those who see the subversion of texts and canon as a form of punk-style writing, DiFilippo's steam has punk in spades: to pair up Whitman and Dickinson is some form of poetry heresy, I'm pretty sure, if one considered nothing other than their poetry on the quintessential steam technology, the locomotive. According to Ferris Cronkite, Whitman's "To A Locomotive in Winter" is a the response of a "worshipper" of the train (171), whereas Patrick F. O'Connell sees Dickinson's "I like to see it lap the miles" as a critique "about the theme of progress, as exemplified by the train" which is "devastating in its irony" (470). Whitman is characterized by Cronkite as the technophile, and Dickinson by O'Connell as the technophobe. This distinction encapsulates the polarity these poets represent, though one could find a number of other topics to establish the distance between them.
A reader without background on these giants of American verse will still grasp the strangeness of Whitman and Dickinson as couple, but they'll miss the immediate humor of moments like the opening scene: Dickinson wakes to find Whitman, "a huge hairy bearded barbarian, utterly and shamelessly naked save for a black floppy wide-brimmed hat" bathing in the fountain in front of her home (240). She is scandalized until she learns Whitman's identity, her shock turning to hope of a peer, perhaps a soul-mate, to share her poetry with. DiFillipo's use of both poet's writings is brilliant - they are interposed throughout "Walt and Emily" as actual poetry, inner ruminations, and sometimes spoken musings or responses. Again, the story is intelligible without a thorough knowledge of Whitman and Dickinson's poetry, but aficionados of these poets will have moments akin to the Marvel fanboy watching X-Men movies and catching a glimpse of Colossus or Kitty Pryde.
However, don't let these diversions into the esoterica of poetry and literary history dissuade you from reading "Walt and Emily," or anything else in The Steampunk Trilogy: as I say, the reading is intertextually enriched by knowing the sources DiFilippo is drawing from, such as H.P. Lovecraft, but the experience is rich enough without that knowledge. I would argue instead, that such richness lends itself to a deeper reading experience. During a second reading, try googling any line you suspect is poetry, and then follow up on any poem you find, looking into explications of those poems. In this way, "Walt and Emily" serves as a door to the wonderful world of poetry.
