supernatural, mystery series

I can't remember the author's name. Books are about a woman with tea shop, son and daughter. Daughter into astronomy. Son (I think) also in touch with supernatural. Woman's dead grandmother keeps in touch. I remember the author's name to be something like galnone.

Ghost of a Chance by Yasmine Galenorn

Wrong touchstone came up on the title, try http://www.librarything.com/work/95123/book/1246688

Ghost of a Chance - click the (others) link and it's about halfway down the list.

Thanks so much. I didn't realize that this was posted twice -- I thought I deleted this posting, so re-did it. I do appreciate your help.

Welcome. Yeah, double-posts aren't all that uncommon - double threads are rarer but not unknown. I just wanted to get all the answers in one post, for simplicity's sake.
