Tessa has written a number of books about cycle awareness for girls and women. Her newest book is Ruby Luna's Odyssey, which is for girls (14+) to encourage getting to know your own body first before someone else's and to discover the pleasure in everyday sensations like the flow of water in the shower or a lovely snuggly blanket as a gentle route into discovering pleasurable intimate feelings in the future. Big topics in a gentle poetic way with white space, watercolour illustrations and space for journaling to lessen the potential feeling of overwhelm.
