The book is written like a mystery. Hints of possible romance between Emma and Knightley were sprinkled all over the chapters, but of course, we don't know for sure until the very end!
Emma also shows the dangers of poking around in other people's personal affairs. It is a classic.
The great thing about Jane Austen is that all of her books are written in a different style. Usually, when an author writes several books in the same time period, they are all written alike. But all of Jane Austen's are unique!
