Concubine Beats King (слэш)

Helaena discovers an old valyrian custom that could save her the misfortune of being forced to marry her brother or her nephew. If it also happens to avoid a civil war and help said brother and nephew be together, well, more the better.

Edit: Doing a bit of editing to the earlier chapters right now. No plot is changing. Just smut and a bit more context being added. I still have the OG version and you can hit me up on Tumblr for a copy if you're concerned/want to compare for any reason. Major changes will be mentioned in the chapter notes for those interested.
