The Eleventh Plague is one of those books that are a great idea, but lack that certain spark in the execution. I won't resummarise the story, but in short it is what I call a 'soft apocalypse' - although the world is harsh and survival is an ongoing battle, there's nothing overly disturbing about this book. The world building is OK - there is information on how the world ended up in the toilet, but there's no real sense of struggle or atmosphere and it reads more like a small-town saga.
Stephen is an average lead character - he is loyal, brave and smart, but there's no real sign of a personality underneath those characteristics. Jenny isn't as much the firecracker I expected from the blurb - she's a rebel in Settler's Landing but the attempt to make her witty and smart-arsey falls a little flat in places.
The writing was probably the high point of the story for me, free-flowing and uncomplicated, there's a feeling of continuity even in the slower passages.
Overall, there's no screaming faults with this book, but it's not going to be a memorable read for me.
