The Trinity Trilogy, by Fiona McIntosh

Betrayal, Revenge, Destiny

Fiona McIntosh is an Australian author of fantasy, I hadn't read any of her books before.

This is reasonably well written fairly standard fantasy.

The plotting in the first book screams "first novel" to me: for example, there's not enough background, and the main character gets a new best friend in a day or two.

The other two books are much better, with some interesting plot twists.

Entertaining.
