In 2016 Szablowski’s book "Sprawiedliwi zdrajcy. Sąsiedzi z Wołynia" (“Righteous Traitors. Neighbours from Volhynia”) was published. It depicts the fate of the victims and witnesses of the 1943-1944 massacres of Poles in Volhynia. Szabłowski’s main focus is on Ukrainians who at great personal risk provided help to their neighbours, Polish or Jewish. The book was awarded Terena Torańska Newseek Prize in the same year and is considered some of the best reporting of the massacres of Poles in Volhynia.
