Ce livre est la transition parfaite entre la saga Harry Potter et la trilogie des Magiciens. [...] En plus de tout ça, on trouve, en vrac : des références culturelles géniales, l'utilisation de la technologie par les sorciers, une guerre inter-espèces, la lutte contre le sexisme, des super-héros discrets, quelques insultes bien envoyées [...] un roman one-shot à lire absolument pour tous ceux qui aiment la magie, les histoires de grands ados (les héros sont majeurs) et, ok, les histoires d'amour un peu.
Divine Substance constitutes the third volume of interviews given by Yvonne Trubert for the Book of Invitation to Life, internal journal of the non-profit association Invitation to Life. Through themes such as Drugs and Alcohol, Depression, Adolescence and Relationships, Yvonne Trubert proposes elements of contemplation that vary from daily life to the most complex questions about one's destiny. Throughout, two subjects dominate : the power of love and divine presence. These chronicles are directed to those who are in a quest for the absolute and to those who embark on this extraordinary journey with the goal of reuniting the once broken link between God and His Children. Thus, Yvonne Trubert invites her readers to understand that "God wanted to put his substance in our galaxy and that He created the costume that best fits this substance : humanity."
Since 1976, Yvonne Trubert has devoted herself to others by listening to them and comforting them. In 1983, with the help of some close friends, she founded an association, Invitation to Life, also called IVI and recognized as an association in the general interest by the French government. Through her actions and her writing, she spread hope throughout France and the world until her death in august of 2009.
