What is love? What is true peace? Is there any alternative to the doomsday? You may find the answers to those questions by reading this story, which featured a Japanese youth who traveled to Sarajevo in 1996. Sarajevo is the capital of Bosnia and Hercegovina and is located in eastern Europe. It is a city where different ethnic groups and religions lived together peacefully even during the former Yugoslavia conflict. This is a science fiction based on my actual visits to the city and the other cities in the Former Yugoslav countries in 1995 and 1996, and fiction featuring two alien groups. One tries to destroy almost all humans while the other tries to save all. Some parts of the story were made on facts. I am sure you can enjoy the fresh teenage drama while thinking about such above mentioned serious themes. You may also wonder a bit about the mystery of the universe after reading this novel.
