This is a story about a girl called Scarlet. She’s 9 years old, just like you, if you’re 9. If you’re not 9, then she’s more like someone else who is 9. She has red hair, just like you, unless your hair is brown. She is 127 centimetres tall, just like you, unless you’re taller or shorter. And she is as smart as a shiny button, just like you. Scarlet only responds to the advert at the back of the Beano for the role of Defender of the Universe to prove to her annoying younger brother that it’s not a real thing… so she’s a little surprised to be told that she’s got the job and is now responsible for the safety of the entire galaxy. Along with her co-Defender Jasper, Pom-Pom, the cutest alien in existence, and Bot, the cleverest AI robot that’s ever been invented, Scarlet is thrown into a whirlwind adventure that takes her to the furthest reaches of the cosmos and back again.
