Ruby Luna is curious about bodies and particularly about the lower part of her body and what she cannot see inside. This illustrated children's book introduces the correct words for female anatomy through humour, fun actions and watercolour paintings, giving children a language for girls' bodies and their cyclical nature, and a knowledge of what is where!

There are two levels of text on each page for different ages or reading abilities. There is an action on each page to keep children engaged in the content and keep the subject light, and amazing facts to entertain and encourage body positivity. Aimed at 5-10 year olds to support talking about bodies while young minds are curious. The illustrations include different skin colours so that all children feel represented.
