Three Sister?

[nightrayne]

Read a book ages ago in the old school sci fi/fantasy genre popular in the 90s or so. Can’t remember a whole lot about the plot anymore but could have sworn the book was called the Three Sisters. Definitely set in a fantasy world with one sister being I believe a warrior/soldier, another may have been a healer, and the third was more of a helpless female/seductress in the way a lot of female characters were written in that time period. Not sure if anyone knows what I’m talking about but have googled so much and still can’t find it!
