From the introduction:
Spark is a roleplaying, storytelling game with a lot of moving parts. The book starts with the Introduction where I explain what the game is about and what you need to start playing.
After that, I show you how you can create your own Setting or use a premade one. Each of the players creates their own Characters who interact with each and with the setting.
The Gameplay chapter explains how you actually get to playing. This is followed by Guidance helps you have more fun while you play the game.
Lastly, there is a series of three premade settings (NeoNippon, Old Cold City & The Republic of the Elements) that you can use for your game.
The end of the book has a series of appendixes including various templates, sheets, a glossary of terms and an index. There is a credits section for the fine people who helped me refine the game.
