Such a good book. 
 I'm really glad I picked this book up - post-apocalyptic fiction can be one of the best genres out there, or completely awful (the latter category mostly applying to the million and one YA spinoffs that followed the success of the hunger games, dominated by love triangles). 
 This book is following on from Burial Rites as a "book that reminds me of something by Margaret Atwood" - in this case, the MaddAddam trilogy, and beyond the basic premise (disease kills almost everyone, we follow the survivors, there are cults), the way in which the story jumps about, between time and place and character, gradually building up to a complete picture, is reminiscent too. 
 I loved the character of Kirsten, still managing to do what she loves, despite the way in which the world has changed, and I enjoyed how much of Arthur Leander's life we see played out - despite the fact he dies in the first chapter (it's not a spoiler if it happens in the first chapter!). 
 I would have loved the book to be at least twice as long, to explore the characters and their relationships with one another, and exploring how a semblance of order came about in the different communities following the collapse of civilisation - and that's the only criticism I have of this book.
