Here's a polished Amazon/KDP description you can use:
Sage Jacobs is the girl everyone likes - but nobody quite sees.
Bright, funny and endlessly curious, thirteen-year-old Sage is also forgetful, distracted and constantly being told to focus, organise herself and try harder. She loses things, misses instructions and drifts off at the worst possible moments. Everyone assumes that is simply who she is.
Then a giant ocean sunfish appears in Cape Town's harbour.
Sage becomes fascinated by the strange, awkward fish that seems just as misunderstood as she feels. One sunfish becomes several. Questions become notebooks. Notebooks become patterns. And Sage begins to notice connections that the adults around her have missed.
As she is drawn deeper into the mystery of the harbour, Sage starts to discover something equally important about herself: being different does not mean being incapable, and being overlooked does not mean having nothing worth hearing.
Set against the coastline, aquarium and harbour of Cape Town, Sage and the Sunfish is a warm, funny and thoughtful coming-of-age story about curiosity, family, friendship, neurodivergent experience, and learning to ask a better question:
Not "Why can't you just do this?" - but "What do you need?"
