While we technically have enough multi-author books to run a modest poll, what would be more awesome is if we could get just a FEW more suggestions on here.
Or just stop by the nomination post and see what people have offered up that you might like to second.
Any book with more than one author or a series where EACH book had more than one author (not different authors for different books) may be nominated. Full rules are over there on the original page.
Please please please please leave new nominations or seconds on the original post rather than here, so everything is in one spot when I go to set up the poll. My little two-volt brain overloads pretty easily.
ETA: Please pay no attention to the horrid spelling/spellcheck fail that happened in the URL.
