More information to be added as it becomes available.
KK will be at Dragon*Con this Labor Day weekend, September 1-4, 2017. She will be on two panels as well as accepting questions from aspiring writers.
KK mentioned in chat this past Sunday that she has been invited to Chessiecon this year (formerly Darkover). It will be held at the Red Lion Hotel Baltimore North from 23 November 2018 to 25 November 2018. Con website: http://chessiecon.org/index.html
I think she said she was also going to be at Dragon*Con this year (as usual), which starts 30 August 2018 and runs through 3 September and is held in downtown Atlanta (across multiple hotels/conference centers), but I don't see her name on their site, so I'm looking into it and will update when I know (or one of the other admins will).
