Lost Authors: WE NEED YOUR HELP!

Help! No, I'm not lost, but it seems that I've lost some authors. I'm a slightly OCD list maker when it comes to reading. I have color coded lists by author, series name, pre-ordered, TBR, etc. But sometimes, even after looking on author websites, publisher websites, GoodReads, Fantastic Fiction, and other sites, I just can't find out if an author is coming up with a new book or if their site is gone completely. So I'm here asking for help. If you know what's going on with an author let us know.
I always have this horrible feeling that one day, an author will pass away and we won't know about it. I feel like when I read their words that I get closer to them, even through their characters. I'd hate to think that they'd be lost and I wouldn't know it. I don't know why, but that bothers me.I know life intercedes, authors change lives, and I totally get that. But I just wanted to know and others wanted to know as well.
Okay here it goes:
Anna Windor:
I love her paranormals. I've been to her site, and can't find it updated. I'd love to know if she has more books on the way and if she's okay. Yes, I worry.
Lisa Kleypas:
I know she's doing her contemporary series now that I LOVE. Anyone heard anything about her historicals?
Denise Belinda McDonald:
Love her westerns. Anyone heard any updates?
Charlene Teglia:
Anyone heard about her Shadow Guardians series?

Linda Winfree:
I can't seem to find her website anymore
That's all I have for now. I love these authors and would love to know if you'd heard anything about those series I mentioned LOL. Also, if you have an author you need help finding book information on, put it in the comments and I'll update the post.
