Rosie Kessous (Author) Rosie is a primary school teacher living in Lancaster with her husband Samir and their cat Kendrick. She is currently studying for a masters and PhD in Education and Social Justice. This is whilst working as Joint Country Co-ordinator for Days for Girls (DfG) UK. DfG is an International Charity providing women's health education, preferably delivered by local women, alongside washable sanitary towels produced by volunteers in developed countries for those in need. Rosie's training as an Ambassador of Women's Health Educator and subsequent distribution of washable sanitary pads on a trip to Kenya inspired her text for 'That Time of the Month'. She recognised the need for a comprehensive, accessible and engaging book for young girls about menstruation. Her collaboration with Arianna is her first book for children. Arianna Vettraino (Illustrator) Arianna is an illustrator based in Edinburgh. She believes deeply in the powerful role children's books can play in helping to educate, inform, and inspire young people; and hopes to use her illustrations for this purpose. 'That Time of the Month' is her first children's book which she created whilst studying at university. After reaching out to the charity Days For Girls (UK), expressing her desire to create a book on periods, Arianna was put in contact with Rosie (the author), who shared the belief that a picture book aiming to demystify and encourage openness about periods was needed.
