Who hasn’t been curious about the unknown, anonymous people that by chance end up together in public transit? Who are they? What are they like?

The blue line is a metro line. It is also the framework of a series of stories that stem from the beginning of a journey. As the metro advances, the protagonists become part of the novel without their knowledge and the stories grow, converge, avoid each other, and change each other without anyone realizing it. Finally, all the cards are marked and the reader knows the characters’ past, present and future. That’s what Blue Line is –a metro car full of lives, and, as such, full of stories.
