Please add cover and fix title

[Brynhild]

Please add the cover and fix the missing words and spelling mistakes in the title of this book. The correct title, as seen in the cover, is "Confesiones públicas de una mujer de mediana edad".

Amazon cover: https://m.media-amazon.com/images/I/6...

Amazon entry for the book: https://www.amazon.es/Confesiones-púb...

Thanks!
