Alistair Reynolds takes relativistic space travel very seriously and it adds natural tension and scale to his work. House of Suns worked better for me than Pushing Ice mainly due to the strength of the characters, there is emotional depth and empathy here that I couldn't find in the other book.

At this point in the series Banks has fully realised his vision for the Culture and it is glorious.

Having watched the first season of the TV show I was pleasantly surprised by how fast paced the book is. I don't think the characters are particularly well rounded but I'm here primarily for the setting and that carries the narrative throughout.
