Kea's Flight by John C Ricker and Erika Hammerschmidt. Amazon UK
A whole new take on population and abortion issues, set in a dystopian future not so far from our own. The standpoint from which the book is written is that of a young girl growing up with a perceived disability in a work in which potentially disabled foetuses are grown to birth date in an uterine replicator, then shipped off to a new planet, growing up on the spaceship. Thought provoking, well written, and even witty. Well worth getting.
This thread has provoked me to read this book again. Time well spent.
More science in this one:
Actually three books, set in the Liaden universe Fledgling, Saltation, and Ghost Ship, by Sharon Lee and Steve Miller. I was possibly influenced by the respect with which pilots are treated by the other characters. Again, a book with a teenage girl as the protagonist. Somewhat YA, but none the worse for that.
