Biography of X

This novel has pretty much everything: an alternate history setting that is at times omnipresent and a detail at others ; a mysterious contemporary artist ; many LGBTQ+ characters ; drama and love. It weaves brilliantly facts and fiction, real artists and writers (oh hello David Bowie & Susan Sontag) and completely imaginary characters (or are they?), and manages to be serious with obvious satirical elements. Very enjoyable.
