Dinosaur Planet Survivors, by Anne McCaffrey
I just had to find out what happened to Lunzie in the last book I read. And of course I had the next one on my shelf just waiting for me. There is a book that goes before this one called "Dinosaur Planet" that starts near the end of The Death of Sleep and ends in the same spot. But as soon as I started it I realized I'd read it a while ago! So I happily skipped to the next book.
I think I really just have to echo what I said about the last book. It's a little drier than a lot of her books, but it's still a good read. It's like there's just enough to make me want to know more about the characters. Kinda frustrating!
