I come to think of the The Black Trillium written by
Marion Zimmer
Bradley ,
Julian May and
Andre Norton , which is about a terrible regicide. The murdered king's triplent daughters witness the murder but manage to flee each to different parts of the kingdom.
The books centers on how thy each of the triplents go through a development finding out their place in the world and the path they each were chosen for from the beginning of time.
In the end they meet anew and as one force break the rule of evil.
An interesting tale indeed if one has a taste for fantasy.
Their names are:
Haramis, Kadiya, Anigel
