In "As Sibilas", Mónica Baldaque shares affectionate memories of her mother, Agustina Bessa-Luís, revealing the universe of the thinker and writer through biographical sketches, diaries and her own illustrations. The work highlights the influence of Aunt Amélia, the inspiration for the famous Sibyl, whose death Agustina predicted with remarkable accuracy in her most famous novel. This book is part of the celebrations for Agustina Bessa-Luís' centenary.

Mónica Baldaque was born in the Douro, in Ariz, Peso da Régua. The Douro is of fundamental importance in her work as a painter, which is evident in much of her work, some of which has been published in books and catalogs.

Professionally, she is linked to museology, serving as the main museum curator. She has held management positions, currently in the municipal museums of Porto. She is on the board of the Association of Friends of the Douro Museum and the cultural council of the Eça de Queiroz Foundation.
