Each map presents its own challenges, but this map for Kevin Hearne's Iron Druid Chronicles #5: Trapped was perhaps the most challenging one yet. I had so much information that needed to be crammed into one small paperback page, but I also wanted it to hearken back to the elegance of the ancient Norse aesthetic, which is more decorative and stylized than informational. It was a tough balance to walk, but I love where I came out in the end! The knotwork alone took a solid week. My brain was bleeding.
