What is the author's style in The Hare with Amber Eyes: A Family's Century of Art and Loss by Edmund de Waal?

"The Hare with Amber Eyes," is written in the first person. The author, Edmund de Waal, is a member of the once prominent Ephrussi family which had its roots in Odessa, Russia. As he relates the history of his family as it was revealed to him, the genuineness of his emotions is without question. The family was Jewish and enjoyed soaring successes in first the export business in Odessa and then later as the proprietors of hugely successful banking operations in the capitals of Europe.
