Your name is Adam Luce.

The Year is 1923, and you're on your way to Berlin, which the guide books and newspapers have come to call the World Capital of Sin.

Your mission is to learn the secrets of manufacturing the new wonder drug, aspirin. You have a degree in chemistry, you have a letter of introduction to the world's largest chemical cartel, and you're prepared to accomplish that mission. But you're not prepared for Charlotte, nor for the secrets she'll share.

And nobody told you that you'd have to save the world.
