Book cosplay is LOVE. Oh yes, it is. I have about a MILLION picked out to make eventually. And I love to see someone I recognize from a book. Just so I can fangirl at them. :3
I'm working on Sarra Liwellan right now (from Exiles: The Ruins of Ambrai by Melanie Rawn). Lined up to do in the next couple years:
Mord-Sith in all three leather outfits (red, white and brown) from The Sword of Truth Series by Terry Goodkind
Shota the Witch woman, from the same series
Fenchurch from Hitchhiker's Guide to the Galaxy Trilogy (as soon as I figure out how to walk on air)
Alanna from Tamora Pierce's book of the same name
I also have a few Grimm Fairy Tale character's picked out, but I'm not really sure if they count as "book" cosplay. ^_^
"Not a word."
