In 2015, Carey started drawing fan art of the popular Dungeons & Dragons Podcast The Adventure Zone by Justin, Travis and Griffin McElroy, and their father Clint McElroy. When the idea came up of turning the successful story into a graphic novel, the McElroy family approached Pietsch for the artwork. She had previously collaborated with them to design a poster for their live shows of The Adventure Zone as well as My Brother, My Brother and Me.[8]"We were spending so much time sending each other links to her stuff we figured it would be easier to just collaborate with her. We realized she "gets it"..."[9]
The first part of the graphic novel series, The Adventure Zone: Here There Be Gerblins, written by the McElroys and illustrated by Pietsch, was released in July 2018 and published by First Second Books. It quickly topped the New York Times' Paperback Trade Fiction Best-Sellers list, and came third overall in the Combined Print and E-Book Fiction list, the highest placement for a graphic novel on the fiction list to date.[10][11]
