Metro 2034 by Dmitry Glukhovsky
This book takes place one year after the events in Metro 2033 and let us follow some of the inhabitants of Sevastopolskaya station. The weapons caravans and communications with the rest of the metro is cut off and Hunter and and old writer called Homer try to find out why. Hunter is still in pain from his encounters with the Dark Ones and Homer is looking for a hero to inspire him for the book he is trying to write.
Good but not as great as the first Metro book. It loose something when it focus on humans and not the Metro as the most important character.
