Has been known to dissolve into the physical pages of books.
Is good at tucking herself into the stacks and retreating to reading nooks.
Blends in at coffee shops where her voice can be drowned out by the grinding and the steaming.
Can become indistinguishable in the dark of theatres, in the quiet shuffle of art galleries, the finger-snapping of poetry readings, the hum and jostle of the Tube.
