Six had already lost her CĂȘpan when the second scar started coming through and she hardly noticed the difference in her agony. She still had to stay out of sight - it wouldn't do for the natives to see her glowing after all - but that was easy when you had invisibility.

Only it didn't seem to work when the scars were coming through - something that took longer for her to realise than it should have.

It wasn't until several hours later that she realised and within minutes she had upped and left the town, barely stopping to pack the most important things.

She tried to never rely on her invisibility again - she'd learnt her lesson.
