At nine years old, she was picking up Jane Eyre.

And just the other day, Rosamund found this book that Ella had been reading.

It was called The Observer Book of Genius.

But a few years before all this, Ella's life had taken a turn.

It started in October 2010, when she was six years old.

Ella and her mum had gone to visit the Monument to the Great Fire of London.

It's this tall tower, and to get to the top, you have to walk up more than 300 steps.

So together, they were climbing this tall tower.

But weirdly, Ella was struggling.

She'd been a little sick, had a bit of a cough.

That night on the way home, Ella fell asleep on the train, which was also strange.

And from there...

Things got bad.

Quickly.

That little cough that Ella had turned into these terrible coughing fits that seemed to come out of nowhere.

Sometimes she'd cough so hard that she couldn't breathe.

And because oxygen wasn't getting into her brain, sometimes she'd have a seizure and even pass out.

28 times?

So she had hundreds of attacks.

And the scariest part of this was that Rosamund didn't know why any of this was happening.
