With a writing career spanning over thirty years and more than seventy works brought out by the leading publishers in Greece, she skilfully combines imagination, humour and the absurd within a framework where the childlike spirit experiences its happiest moments.During her long and very successful career in state educational television the scripts she wrote made an important contribution to children's literature.

She can be numbered amongst those authors whose books appear to be addressed to children by children themselves, while another element that gives her work exceptional value is its appeal to a variety of ages. Indeed, most of her books can be read with pleasure by adults. She has a way of leaving areas of vagueness into which each age group can fit its own experiences in life; in parallel with the reading these become creatively transformed into literary experiences.

The bulk of her work consists of illustrated books for children, and these can be divided into two main categories: literary and informative. In the first category the literary quality of the stories is noteworthy. Their language, simple, unadorned and at times eccentric, has elements of the traditional but is chiefly modern in style. Influenced both by mythology and worldwide traditions of storytelling, with personal references and with sudden breaks in the narrative form in some of the books, it aims above all at giving pleasure by its originality and happy refusal to conform to norms and secondarily, and indirectly, at arousing readers' social awareness.
In all her books Sophia Madouvalou shows that she knows how to say 'serious' things and basic truths in a simple way and by means of playful and creative devices. For example, her verse story Riko Kokoriko makes an important contribution to children's multicultural education and points out some unpleasant truths about a deeply self-centred society, but it does so in a humorous way and above all the book is an entertaining read.

In The Teacher Whose Head Became a Saucepan she gives us perhaps the most 'with it' and subversive teacher in Greek children's literature – a teacher filled with love for her pupils and who transforms them into genuine creators, though at no mean cost to her nerves, of course! The book breathes love and friendship, tolerance for others and above all self-respect. Its lyrical realism, with situations and events clothed in inventive humour, recall some of the best moments in classic series such as Goscinny's Le Petit Nicolas.

In the second, informative, category of books the author succeeds in a like manner in combining the acquisition of knowledge with humour and imagination. She does not choose the easy solution of merely presenting facts but ingeniously packages the knowledge to be imparted in the form of stories so that it is effortlessly transmitted into the receptive mind of the young reader.

In all Sophia Madouvalou's books there are two stylistic elements that set them apart: humour and imagination which combine creatively with a third element that has an ideological content connected with emotional and social awareness and which skilfully weaves itself into their various themes. As far as the humour is concerned, it is both original and subversive. In her books it may be presented either at a lexical, phonological or semantic level or in situations occurring in the story, through excess, exaggeration, absurdity and ongoing astonishment. These forms of highly literary humour, always expressed in a form accessible to children, amuse and entertain the reader and often make caustic comments on problems relating either to the selfishness of modern people or to society as a whole and the need for cooperation and acceptance of people different from ourselves.

Sophia Madouvalou is a distinctive presence in Greek literature for children, and, we believe, on an international level as well. She is a creator whose talents are at their height and who on the one hand has contributed in various respects to its development and increasing popularity and on the other hand, and more importantly, by combining imagination and humour in its various forms in her books has touched on contemporary themes dealing either with personal or emotional matters or with children's social awareness in such a manner as to enable them to better know themselves, those around them and the complex world in which we live today.
