There are things that happen in the world that are difficult and sometimes impossible to explain. At times, we are confronted with circumstances or situations over which we have no control. How we deal with those situations reveals much about our strongest beliefs, our dreams, and our fears. This collection of short stories explores specific instances of involvement with or belief in the supernatural in one North African country. The tales, all claiming to be true, were collected over several years while the author was living in Morocco.

This project started as a language learning experiment. Matthew Helmke was sitting in a cafe with a Moroccan having a discussion in Moroccan Arabic. The friend told a joke and it was quickly discovered that vocabulary alone would not insure an understanding of humor. This prompted a question, "What did I miss?" In this book, Matthew Helmke explores the hidden aspects of Moroccan culture. These are the things that Moroccans know inherently, without being taught. The result is an intriguing look through the eyes of an American trying to make sense of Moroccan culture.
