At 26 Martín Vargas Street in Madrid, Lena, Hugo, Ramiro, Camelia and Jara have managed to turn the flat they share into a space where they share their lives. Now in their 40s, they are living together out of necessity, and also because it is part of their way of understanding coexistence and personal relationships. But Jara's situation and character are more unstable: she hasn't worked for a long time and is always on edge. Is that why she has left without warning and without leaving any clue of her whereabouts? This book is a pulse of energy that leads us to the paths where fragility and strength, the difficult and the possible, and perseverance and loyalty in their various forms come together. A moving novel made of common stories, its intensity does not lie in its darkest, murkiest moments; instead, sometimes, many times, in those moments where respect, laughter, chat, happiness, mutual support or shared anger shine.
