When we are children (but also later), it addresses situations encountered a necessarily influenced by personal experience look. Imagine what happens to a little girl that her father deposited in the (almost) unknown so it clears the floor at the end of the nth pregnancy of his mother.
As the days, she notices the differences, enjoy while receiving shadows in this foster home where one shows so benevolent towards her.
Just like the little girl, the reader is drawn into the family of which we know nothing, but we understand why she lives (lived) a drama. So we let ourselves go, small in small subtle touch subtle touch. Develop hypotheses, imagines the events, the hope and the fear.
When comes the end of the summer, even if the veil was lifted, it wants more.
A great success.
