Glorious Angels, by Justina Robson

Second paragraph of third chapter:

‘My father was a soldier in the war, a hero,’ a young recruit was saying eagerly. He was seated at the far end of the trestle where the lunch was being laid waste by himself and his twenty-four troopmates.

Probably more a reflection of my state of mind than the quality of the writing, but I’ve given up on this not quite half way through when I realised I had completely lost track of the characters and their motivations. Some excellent sex (in the book! in the book!) kept my attention for slightly longer than might otherwise have been the case.
