Today I have a trio of venerable V authors for you.
Carrie Vaughn is the author of the Kitty Norville urban fantasy series about a female werewolf. I've read several books in the series but am a few books behind. Apparently she will be ending the series soon, so it might be time to catch up on the ones I've missed. I also like her Golden Age superhero series. She's also written for the Wild Cards series, and one of her short stories earned a Hugo nomination. Learn more about her and her work on her website, Wikipedia, and Amazon.
Joan Vinge was married to SF writer Vernor Vinge and is currently married to a former SF editor. She won the Hugo for The Snow Queen; I have both that book and the sequel, The Summer Queen, in my collection. You can learn more about her and her work on her website, Wikipedia, and Amazon.
Last but not least is French-born Canadian science fiction writer Elisabeth Vonarburg. I met her at WisCon one year and was lucky enough to get her to autograph In the Mother's Land for me. I don't think she has an English website or a lot of books that have been translated into English. You can learn more about her on Wikipedia and find her work on Amazon.
Please add any other female V SF authors you can think of in the comments below.
