Right now, I'm reading Mortal Fire by Elizabeth Knox and An Officer and a Spy by Robert Harris.
Mortal Fire is set in the same universe as Knox's Dreamhunter/Dreamquake novels, but about 40-50 years into the future. I'm only about two chapters in but it's promising.
An Officer and a Spy is based on the 19th century Dreyfus treason case in France. My reading has been a bit patchy of it, but if I get the chance to sit down and really get stuck in, I'm expecting to get caught up in the story.
What are you reading?
