Eloy Moreno's debut novel, which made him famous in Spain. A story about escaping from the confined space of one’s own life into a vast world. About a prisoner of routine who decided to throw off his shackles. Here is a fascinating novel about a man whose life is calculated on 445 m2 and 60 free minutes a day, which he has after work and household duties. And only one lost green pen helps him change everything. Problems exist for a person to overcome them, for the sake of pleasure, in order to feel alive. It's time to stop comparing your life with the one you would like to have and start taking action instead of putting it off for later.
