Read for the Big Fun in a Little Package Novella Challenge.
This was actually the first book in this series I read. It so absorbed me that I sought out the rest of the series wherever I found it.
Once again, a re-read as an adult was a valuable experience. As a child, I absorbed the idea how a few small changes, and well-chosen acts of compassion at a moment of choice, could have far-reaching effects. As a Pagan it has even influenced my ideas about how my religious view of magic works. As an adult, I also gleaned how unhappy circumstances or poor choices can reverberate through generations to create damaging effects; and how happy circumstances and positive choices can heal some of that damage.
A powerful book that is not only about time travel, but that says a lot about life and the human condition.
Highly recommended to everyone.
