Lost graphic novel 'Saga: Volume 1' with a black cover and striking illustrations near the bench on Main Street in Northeast SD.

I realized I lost my beloved graphic novel, 'Saga: Volume 1' while walking my dog in the park near Main Street in Northeast SD yesterday afternoon. It has a black cover with striking illustrations on the front, and I was just a few feet away from the bench where I usually sit. If anyone finds it, I would really appreciate getting it back—it means a lot to me!
