The Causal Angel

A widescreen-baroque grandeur... A maddening, dizzying and dazzling novel * SFX *
Hannu Rajaniemi is without question one of the smartest and most exciting writers working in science fiction as we speak, and I can't wait to see what he does next. * Tor.com *
The bottom line for The Causal Angel and the Jean Le Flambeur series: it's evocative and can be mind-bogglingly at times but this creates a highly addictive air around it, and once you get through to the fine details you will be amazed. This is must read science fiction. * The Book Plank *
With The Quantum Thief, Hannu Rajaniemi set a new standard for science fiction that dared to imagine a post-human future. With its sequel, The Fractal Prince, he successfully built on his narrative foundations to add a greater depth to his characters - not least the gentleman thief Jean le Flambeur - and an added strength to his ideas. So it's something of a relief to report that the trilogy's conclusion, The Causal Angel, doesn't disappoint. * The Skinny *
It's all things to all people, opening up to deliver whatever you want from it - action and adventure, memorable characters, rich stories and weighty themes. This is what Science Fiction should aspire to. * SF Crowsnest *
The author, who has a PhD in string theory, uses the tropes of the genre to present cutting-edge explorations of post-humanism, quantum physics and cybernetics. The plot is pell-mell, the theory intellectually challenging, and Flambeur appears as a fully rounded human being, with hopes and desires, strengths and flaws. * The Guardian *
