Many years ago I randomly picked up the first book in this trilogy and was hooked from the first page. I've since re-read this trilogy many times. Outside of this author and Tolkien I've read few, if any, other fantasy novels; not because I have anything against the genre but because I wouldn't know where to start. I think it can be very hit and miss with fantasy (it irritates me when authors feel they have to use the strangest, most unpronounceable names for their characters and places - it feels like they're trying too hard).
Happily, this book is unpretentious and it's just a good, fun read - nothing too heavy. The heroine of the book is Gemma, who receives a calling to go the southern continent, where she discovers she has magical powers and must learn to use them to overthrow a powerful evil force. The characters are diverse and likeable (well, except for the evil ones of course).
I have a bit of a soft spot for these books; I guess they are 'comfort' books to me, and ones that I turn to every couple of years so I can revisit the characters and their adventures. I would recommend them if you can find them!
