Erica Tapp is passionate about storytelling and Bible teaching. She has spent many years on staff in schools and at large churches in central London and St Albans. The focus of her church work was helping children and young people to read, understand, and love the Bible. She now has three young children of her own to read to, and is active in children's work in her local community in Harrow. Giovana Medeiros was born in Criciuma, Brazil. She graduated in Fashion Design, but later pursued her dream and studied Illustration. She worked for several years creating print designs for apparel, but since 2011 has been dedicating herself to becoming a full time illustrator. Although her work is mostly focused on the children's universe, it has also been applied to different mediums such as books, magazines, textiles, games, and apps.

Aside from her work as an illustrator, she dedicates her free time towards creating autobiographical comics, discovering new recipes, drinking coffee, and travelling.
