S.T.A.L.K.E.R.: Captives of the Zone (diary #1) by Artur Frank

More than 80 books and over 6 million copies of the Stalker book series have sold in Russia and in Germany. 

The official S.T.A.L.K.E.R book series has taken on a new image — graphic novels that will immerse you in the world of the Zone where dangerous anomalies lie in wait for the Stalkers at every turn and where hideous mutants and zombies are on a continuous hunt for man.

A Swedish tourist named Max Cotten vanishes without a trace during the European Football Championship in Kiev. A friend receives his notes contained in a package. Max is alive for now, but will he be for long? Involuntarily, he is in the most dangerous place on Earth — the Zone. Is there a way to freedom amid a man-hunt? Will Max want to leave the Zone or will he risk it all and stay to search for an answer to a lingering question? (etc)
