Nicole Andelfinger was crafting stories as far back as when coloring in the squiggles on your composition book was considered cool. Since then, she's only continued to dwell in the realms of magic, monsters, and myth. When not changing her hair color or writing comics for some of her favorite characters, she works a day job best described as 'emails'. She lives with her absolutely, most decidedly perfect cat in Los Angeles.
