This is an interactive book with YOU as the main character.
After the waters rise, you're just another poor kid living in the flooded under-city. Life is hard every day, especially for a courier like you delivering packages to the under-city's most dangerous neighborhoods while dodging pirate gangs, wild animals and security robots. But today is no normal day. Today you might end up as an explorer, or a froggy, or a trainee manager. Or dead. Or worse. It's your choice. Be careful out there.
