In 2017, the author published Rejwach (Uproar, trans. NS), a book that is difficult to ascribe to one genre. In an interview for the Jewish magazine Chidusz the writer said:
I wrote fiction that turned out to be true. Most of these stories came to me through people. Sometimes I’d also remember something from the past and write fiction inspired by the recollection. Later on it would turn out the stories were in fact true… People would appear and tell me they were the protagonists of my writings.
Rejwach was nominated for the prestigious Nike Literary Award in 2018. The book was staged in 2018 in the Jewish Theatre in Warsaw.
In 2018, Grynberg published the non-fiction book Księga Wyjścia (Exodus, trans. NS), another collection of interviews. He talked to Jews who were forced to leave Poland in March 1968, when the communist government organised an anti-Semitic hate campaign.
In 2020, Grynberg published Poufne (Confidential, trans. NS), a fiction book inspired by the lives of the author’s closest family.
In an interview for Gazeta Wyborcza, Grynberg said:
It’s not like writing my book makes me feel better or anything, although some readers tend to think that. Writing has nothing to do with healing and there is no catharsis. I see it as sharing stories so that we can understand each other better. I believe that if everyone opened the doors to their world just a little bit, we could all finally have some more air.
