I read this book in junior high, and soon forgot most of the important details. What stayed with me was that it was filled with rich imagery of the foggy and mysterious coast of Newfoundland. I remembered that it was my first introduction to the somewhat dark "fairy world" of Celtic legends and mythology, which in the story lived on in an alternate, more real version of our world, and that the protagonist's name began with M. Armed with this information, I tried unsuccessfully to track this book down for a long time. Finally got a hold of it last week, and I was afraid it would be like other disappointing revisits of things that once fascinated me, like re-watching All Dogs Go to Heaven. Turns out it was almost as captivating as the first time I read it, and it was quite fun to "walk around" in that story again and recognize things as I went along.
I would say that the characters could use more depth; I did not really feel much for any of them, except that I think the true protagonist is not Meave, but the mythology itself. There is a lot more feeling and attention given to this rich tradition of stories, how it interacts and compares with religions and ideologies, how it is affected by current problems and how it continues to influence the lives of people who believe it and those who don't.
Therefore, while I found the plot and characters slightly lacking, the setting and the history were wonderful. The pronunciation guide was interesting and helpful, but there were still so many words that I had to skim over without getting to "hear" how they sounded.
I'm glad I found this book again.
