Really really enjoyed this book. I felt it was quite well-written.
Loved the setting and the sprinkles of German-- trotted out my rusty high school German. lol
There are loose ends and unanswered questions at the end, but since the narrator is a young woman relating what happened several years earlier when she was a child, it works. You don't feel like things were missed, it's just that the narrator doesn't have the answers.
A warning, though, it is a bit darker than I expected. Maybe I just didn't read the summary closely, but I expected a lighter book.
Overall, it feels a lot like a modern fairy tale. Definitely recommended.
