I read this book not long ago; I know it's a "children's/YA" book, but I really enjoyed it anyway. I think it's a nice mix of real-life family problems among siblings and a very magical world that one of the siblings enters. I read this right before going to Wales, where the book takes place, and it made my trip that much more "magical."
I didn't expect to like this book when I started it. But I soon found that I couldn't put it down. If anyone doubts that life in the Arizona Territories was hard, read this. It's fiction, but it's based on the author's family history. The protagonist, Sarah Prine, is an incredible woman and I felt like I was missing a friend when I'd finished the book.
