This is my absolute favorite of her various series. This is the third and final installment sadly (other than her short stories, most are on her website, some are published in scifi compilation books) love her characters and adventures, you just don't know what will happen!
I seriously read this trilogy over and over again. I am a huge science fiction fan in all formats, you must check this out!!
BTW, no humans in this series!!!!!!!!!!!! SOOOOOOOO GOOOOOOOOOD!
