Feldman started blogging, and in 2012, she published her autobiography,
Unorthodox: The Scandalous Rejection of My Hasidic Roots, which became a
bestseller and was translated into 30 languages, into Hebrew in 2013. In 2014, she published
Exodus: A Memoir. Her books have been translated into German and well received by German critics, which led to her appearing on various talk shows on German TV. In 2017, she published
Überbitten (roughly translated as "Reconcile"), a German-language expanded version of
Exodus, which she wrote in collaboration with publisher Christian Ruzicska. Feldman said that writing in German was freeing because she could use her broader vocabulary of Yiddish terms that a German readership could understand. She characterized her writing style as old-fashioned, owing to the 18th-century version of Yiddish she grew up with.
Überbitten was well received. The Swiss-German newspaper
Neue Zürcher Zeitung called the book "a report on the long journey to the self, a literary survival guide, and a formidable philosophical-analytic confrontation with one's own history". The 2020
Netflix original miniseries
Unorthodox is loosely based on her autobiography. Netflix also produced a documentary,
Making Unorthodox, that chronicles the creative process and filming, and discussed the differences between the book and the TV series. In November 2023, Feldman appeared along with German vice-chancellor
Robert Habeck on the talk show
Markus Lanz, where they debated the German response to the
Gaza war. Feldman said that the only lesson from the Holocaust must be the unconditional defense of human rights for all. Feldman criticized the
postponed award ceremony for the Palestinian author
Adania Shibli and her novel
Minor Detail at the
Frankfurt Book Fair 2023 and signed the open letter from 1200 intellectuals against it. ==Criticism==
