Fatelessness, is a fine work, but -- unlike Kertész's later works -- ultimately not a truly remarkable one. Nevertheless, in laying the foundation for almost everything he wrote afterwards (and for understanding the man) it remains an essential text. It is good place to start on Kertész, but should be just that: the start. In moving from this book to his later works one moves from a simple, affecting story to true literature, from reality to art.
I differ, a little, in my thoughts on Kertész's debut: I did think it was "remarkable". It was powerfully restrained; György Köves, the Jewish teenage narrator has an authentic and compelling voice; and the ironic distance Kertész's builds through the György's naivety is chilling.
Kertész is very careful, via György, not to describe Buchenwald, where Kertész himself was imprisoned, as "hell". What does that - hell - mean? It is too metaphoriacal, too abstract. György simply describes what happened to him. He doesn't abstract - mythologise - the horror. And it is this device that gives the work its power.
