Emily Jayne and the Kairos Codex (Emily Jayne book 1) is a middle-grade speculative science-fiction novel set in a Milky Way galaxy that is filled with intelligent extraterrestrial life. It has strong and smart girls in lead roles, who like science, technology, engineering and mathematics (STEM). (It has strong and smart male characters too!)  The heroine, 11-year-old Emily Jayne Hutchings, and her cousin Sarah Spiller, need help from their friends Lazar, Samuel and Cindy, to escape evil time travelling aliens and find the one extraterrestrial species that can help them. Emily Jayne and the Kairos Codex is the first book in the Fellowship of the Timeless series. #girlsinSTEM #boysinSTEM

“Emily Jayne and the Kairos Codex is about children, friendship and adventure. It’s about dogs, and the special connection that can exist between people and the canines they love. It’s about neurodivergent kids, those children who don’t fit in with the ‘normal’ kids at school, and it’s about diversity. It’s about a love for and connection with math, astronomy, space and the universe, and a longing to know more and to find life elsewhere.”
