What is the author's style in By the River Piedra I Sat Down and Wept by Paulo Coelho?

The book is written in the first person through the point of view of Pilar. Throughout the book, the reader knows what she is feeling, thinking, and how she is blind to her own logic. She contradicts herself many times, showing the reader that she is going through a lot of turmoil and does not know how to handle herself. This is a very successful method for viewing the evolution of the character. Whenever Pilar faces a new challenge, she approaches it very cautiously at first. She teeters back and forth, showing how she is fighting her heart and her mind. Then, as the book progresses and she is getting better and suppressing her negativity, the reader can see her flourish.
