Uranus, the ice giant, is the coldest planet in the solar system, and also a god in Greek mythology. Uranus also gives its name to Uranism, a concept forged by the first European sexual activist, Karl-Heinrich Ulrichs, in 1864 to define the "third sex." Paul B. Preciado dreams of an apartment on Urano where he can live outside of power relations and the sexual, gender and racial taxonomies that modernity has invented. «My trans condition», says the author, «is a new form of uranism. I'm not a man. I'm not a woman. I'm not heterosexual. I'm not homosexual. I am a dissident of the sex-gender system. I am the multiplicity of the cosmos locked in a binary epistemological and political regime, shouting before you. I am a Uranist in the confines of techno-scientific capitalism.

In this book, which brings together an extensive series of "chronicles of the crossing", he recounts his process of transformation from Beatriz into Paul B., where hormones and the legal name change are as important as writing. This is not only the chronicle of a gender transition, but also that of a planetary transition: Preciado analyzes other processes of political, cultural and sexual mutation, addressing diverse topics, such as the Catalan process, Zapatismo in Mexico, the Greek crisis, Trump's America, new forms of male violence, the technological appropriation of the uterus, the figure of Assange, sex work, the harassment of trans children or the role of museums as engines of a possible cultural revolution.

Paul B. Preciado questions political norms and borders, scrutinizes established social structures and puts them in check in texts that have the forcefulness of proclamation, and a stimulating formal radicality that also questions the limits of the literary.

This is a brave, transgressive and necessary book that starts from a personal experience to question the foundations of a society that excludes heterodoxy, problematizes it and turns it into a disease. This is a book written from the border, from a lucid queer radicality, which seeks to free the body and mind from moral ties and political restrictions.
