I may love The Adventure Zone more than is strictly healthy. What began as a one-off lark by brothers Justin, Travis, and Griffin McElroy (the guys behind the delightful comedy advice podcast My Brother, My Brother, and Me)—what if we played a session of Dungeons & Dragons with our dad (West Virginia radio veteran Clint McElroy) and recorded it?—grew, over the course of three years, into one of the most engaging pieces of long-form genre storytelling I’ve ever encountered.

If you haven’t experienced the saga of the three bumbling adventurers who dubbed themselves “Tres Horny Boys”—fighter Magnus Burnsides (played by Travis), dwarven cleric Merle Highchurch (Clint), and wizard chef Taako (Justin)—I envy you, because their entire journey is now there for you to experience in one 69-episode binge (nice). With Griffin as the beleaguered Dungeon Master, doing his darnedest to keep his constantly goofing family members in line and the plot moving along, the show grew from a relatively straightforward beginning (pulled straight from a beginner’s D&D manual) to encompass dozens of unique characters (of myriad species, sexes, and gender identities—all of them given voice by Griffin), fascinating worldbuilding (Robots! Bugbears! Moon bases! Golems! Magic tacos!), a time-twisting plot, real pathos, and enough references and in-jokes to populate an entire wiki.

With nothing in the way of publicity outside of word-of-mouth, the fanbase grew exponentially, as a passionate group of listeners came together online—and later, in person at live shows and comic-cons—to celebrate the show and share their intricate fan theories and equally intricate fan art.

And though the story is now told, the adventure hasn’t ended: this summer, First Second will release a graphic novel adaptation of the podcast’s first story arc, The Adventure Zone: Here There Be Gerblins [sic], adapted by Clint McElroy and sons and illustrated by Carey Pietsch (Lumberjanes), who also was a part of the writing team.

Fan response to the book has been huge so far—the day it was available for preorder, it jumped into the top 10 on this very website, more than a year out from release. That’s why Barnes & Noble is super stoked to be able to offer both a limited signed edition of the graphic novel as well as, we can now announce, an exclusive collector’s edition featuring a gold foil-stamped cover and a bonus two-sided poster illustrated by Carey Pietsch!

Check out the two-sided exclusive below and get your pre-orders in now—there is a limited supply of the B&N edition, and like a symphony fed to the Voidfish, once they’re gone, they’re gone. Well, except for the whole “memories being magically erased” part. But otherwise. Act now, is what we’re saying.

Anyway, here’s that two-sided poster:

Preorder your preferred flavor of the graphic novel now: the signed edition and the exclusive collector’s edition will both be released on July 17.
