The Apollo Murders

This felt like a mix of fiction and non-fiction given the amount of technical information Chris Hadfield puts into it. The first quarter you could argue that it felt more like a history lesson than a novel but soon after that all that world building really paid off and the thriller element came to the fore. From that point on I loved the plot and characters and never felt you knew how it was going to go or who the good/bad guys were. Highly recommend it for any alternate history fans out there.
