The book opens with Jaq fighting off a vicious attack as she leaves an ethanol factory.

I am not as strong as any of these three men. I don’t stand a chance in a fair fight, but I understand the principles of physics. Energy is force times distance. My legs are the longest levers I have. Power is the rate of energy transfer. I can’t rely on a single kick; I need to deliver frequent blows. Momentum is mass times velocity. I am lighter, so I have to move faster.

They are fighting for gold. I’m fighting for something much more precious. I didn’t come to Brazil because of a gold mine. I came to this country to find my son.

The men are moving again. I can’t wait here to be rescued. I need to defend myself, and I know exactly where to find the most effective weapons.

I run towards the factory.

Jaq uses her understanding of the sugar to ethanol process and all her scientific skills to fight off the 3 assailants. She escapes on a freight train. Follow her rail journey on this magnificent map:

The Malha Paulista freight railway carries almost 3 million tonnes of sugar each year. It connects to the FRS which carries 5 million tonnes of soy and 4 million tonnes of corn. Both connect with the MRA, which carries 121 billion tonnes of iron ore every year. By connecting with the Ferrovia Norte-Sul railway Jaq travels by freight train from the port of Santos on the South Atlantic coast to Palmas in the geographical centre of Brazil.

BT – That is quite the journey is it not? Any train journey is good but this is extra exciting.
