What's the Name of That Book??? discussion

I’m looking for a book series I read quite a while ago(2005?). I know it was a series and it was either y/a fantasy or y/a sci-fi. The main character was a teenager-pretty sure she had red curly hair-as the book series goes on it appears that her younger sister has powers too. I’m pretty sure they had a single dad-the mom died or something before the start of the series-and I know for a fact that in one book(4 or 5 I think) they go to Ireland-dad too-stay in some castle and meet up with others with magic to preform some spell/ceremony that requires a lot of magic. I think while there she starts to get a crush on some Irish guy with dark hair? Help!

Mary, are the sisters twins? For example, The Solstice Cup by Rachel Dunstan Muller?

Mary Ferer, are you still looking for this or did you find it?

This bears a vague resemblance to the early 'Young Wizard' books by Diane Duane. The older girl is called Nita, and has a younger sister called Dairine. In 'A Wizard Abroad' Nita goes to spend the summer with her aunt in Ireland, and meets a wizard called Ronan. In a later book, her Mum dies of cancer

This might be part of the Chronicles of Faerie books by O.R. Melling. Her titles include: Light Bearers Daughter: The Chronicles Of Faerie Book Three and The Book of Dreams, both of which feature a young woman protagonist who has a single father.

(The other books in the series are really good, too!)

No response, moving to Abandoned folder.
