In the round house on Via Saterna in Milan, its Palladian square exterior nothing but a trompe-l'oeil, the sun pierces through the central skylight. Its rays pass three floors unobstructed, before reaching the circle below at the heart of the house: four fingers of water filling a little silver basin. It is here that young Lidia dies, setting an end to her clandestine love affair with the ambitious architect. It is this house that real-estate agent Irene is asked to sell, decades later, as the climate catastrophe escalates, cloaking the divided city in a permanent orange haze. As she faces this new Milan, Irene throws herself into the impossible sale, getting to know Via Saterna intimately-this space that is as unsettling as it is hostile, with the slowly emerging traces of Lidia's interrupted life. In every room of the house, the burden of a mysterious, unresolved past can be felt, remnants of a selfish and manipulative love. The Perfect Circle is a subtly disturbing page-turner, every new page adding a new layer and twist.
