Alma Nilsson is a Swedish author of science fiction erotica based on a fictional future where humans are small-time players in the big-time galaxy. Her books are a part of the Alliance Series which are true to the science fiction genre in that they make the reader question their own morality in the character's situations. There are no heroes or women being rescued in any of her stories, instead readers are led through a maze of alien courting customs, strict religious codes and compromises, often uncomfortable, between men and women to come to solutions that work for both within the confines of Alliance culture. The main themes in her books are; sex, immigration and integration. Each book follows a completely different woman on her individual journey into this alien world.
