I must have read this book three or four times when I was a teen, and then spent the next few years hunting through used bookstores for the rest of the series. I'm so pleased that the author has released them in E-books so I can read the all again.

This is classic optimistic better future sci fi, of the kind that made me love the genre when I was a kid. The characters feel real, and the heroine who is sixteen at the start of the series acts like a sixteen year old, but is still smart, bull-headed and compassionate. I love the adventure, and the world building, and stayed up all hours finishing it, even though I knew by heart what would happen.
