Maybe 3.5, or maybe 4. I enjoyed it, wanted to keep reading and find out what would happen to Mimi and her family. The people and the setting were vivid for me, and the idea of a valley being drowned. But also there were lots of little things that stopped me enjoying it quite so much. Each on their own was minor, but together they seemed to add up. Some clunky writing: (I can't find the actual one) but things like 'They didn't want to come in in the beginning'. A big secret that is revealed right at the end without us suspecting that there is a secret. (The secret is great, and the ambiguity of it is brilliantly handled, but somehow the fact that there weren't any hints about it earlier made it have less of an impact.) The fact that Mimi is so nice. She never rows with anyone, never gets disappointed or angry. I know that's just her character, but it did make me want to shake her.
