This series seems to be ongoing. The first three books on the list are published here, the fourth is not yet published here, but I am not sure that the fourth book will be the last.

1.  The Gift
2. The Riddle
3. The Crow
4. The Singing (only published in Australia as yet)

Will be putting the first three of these on my booklist in a couple of months. (At present I need a short pause to be able to read some of the books I already have.)

Actually The Singing is out here too, I got it from Amazon.

It's the final installment in the series and it was a good ending to a lovely series =) 

 Haven't heard of these...what genre are they....

It's a fantasy series and the protagonist is a girl.

The writer is a poet and you can really see that in her writing, beautiful descriptions. 

If the singer is out here, that is definitely one for my Wishlist. Thanks for the heads up paintmonkey.
