Scarlet Defender of the Universe

This is a story about a girl called Scarlet. She’s nine years old, just like you, if you’re nine. If you’re not nine, then she’s more like someone else who is nine. Her favourite colour is green, just like you, unless your favourite colour is grey, although that seems highly unlikely. 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…
