Really quite interesting! Half of the book was the introduction and other information, but it's essential to reading the book, I think.
Quite loved reading this book, even if I didn't love it as much as his WAY STATION. The sheer humanism and ideas in this are quite wonderful, even if it feels very dated– Feels often too simplistic/naïve, it's filled with Lamarckian thinking, and there are some other flaws that hold it back.
But it's still a very enjoyable novel, and you can't help but forgive its faults. A typical Astounding-era book.
A simple but somehow very captivating/moving story. It could have done without the heavy religious undertones, however.
