Enjoyed this book but felt it was a bit scattered. In the beginning the author reconstructs the lives of her ancestors, based on records she found but also dramatising the things she did not know about. But further on, almost abruptly, she starts her own story and most of the book is about her growing up in Canada. I didn't buy this for the title, but there's very little of Castle Rock and Scotland in it. Instead there are a lot of considerations about farming, settlers, landscape, trees, a lot of Nature. Interesting, but not my kind of themes.
