I've read 5-6 books of Gail Z Martin's and really like them. I have the first 3 of her newer fantasy series on my kindle, since they were all on promo a week or so ago. I'm looking forward to getting to them.
I also think it is really interesting to see how many shorts she does, adding back story and between-book cannon stories as well for the fans. I think that is super-cool and we don't seem to see a lot of that, outside of Brandon Sanderson and a few others these days.
