What is the author's style in The Flame Trees of Thika: Memories of an African Childhood by Elspeth Huxley?

The story is written in first person from Elspeth's point of view. The story is very limited and the perspective never changes. Any details not seen from Elspeth's perspective are presented by Elspeth, realting them to the reader as Elspeth learns about them. The limitation makes Elspeth's character something of a mystery. Though she explains her feelings about particular events and her thoughts on some points, she tends to present more of her observations of others. This gives the reader a very limited view of Elspeth's character.
