Hana Mokrosova studied a literary and publishing secondary school. During her studies, she really enjoyed literature, creative writing, and visiting book fairs as well as various graphic exhibitions. Later she took a degree in Special Education (logopedics, surdopedics, specific learning disabilities). Since then, she has been working with children as a special needs teacher. Both in her job and in her leisure time, she creates books for young and adult readers, and she is also a successful foodblogger, since baking is one of her passions, too.

Helena Harastova is a Czech writer, a translator from English and Russian, and now primarily a mom.

Elena Pokaleva is a professional illustrator, coming from a family where both parents work as artists and create kids' books too. In 2010, Elena moved to Prague (Czech Republic) to start her professional life as an illustrator in Europe and to get new unique experience in studying abroad. Since then, she has had 3 personal exhibitions in Prague, created books, board games, and design products. Elena usually creates her illustrations in two different styles. Sometimes she works with vectors and creates funny simple geometrical illustrations with a help of graphic programs. Sometimes she prefers to become a real "retro" artist, and only works with her hands, painting with tempera, gouache, watercolor pencils on the paper, experimenting with textures, different color effects, materials and collage.
