If you've read the previous book, Last Light, you'll probably enjoy this one too. It's set 10 years after the events of the first one, Alex Scarrow states his reasons why which I thought was a refreshing thing to see - I like it when an author takes time to connect with their readers.
The story itself isn't quite as gripping as Last Light, the sense of urgency is somewhat lacking, possibly due to the nature of the story being 10 years after the chaos and panic of the first story. However, I still found myself eagerly turning each page at 2 and 3 in the morning. There are plenty of "what would you do?" thinkers dotted along the way as the characters struggle through their various paths. I like a story that makes me ponder how I would react in a similar situation.
As with Last Light I thought some of the characters were pretty well fleshed out. Others I wanted to know more about seemed a bit limited in their purpose, needs, desires and so on. The use of dialogue gives the characters good individuality, although I'm not a huge fan of the multiple explanation marks the author uses in his dialogue. The circumstances and character behaviour (if well written) should be enough to tell the reader a situation is tense or not without a lot of !!! at the end of so many bits of dialogue.
Another nit-pick for me is the use of capitols in dialogue. Again this shouldn't be necessary to convey emotion if the writing is strong. Despite this, the dialogue and regional dialects, slang, street talk etc is very well done.
I'm sure the Kindle version has been poorly laid out as there are huge gaps between the paragraphs, more than the first book. I got used to it, sort of. A slightly odd thing is the first person diary entry at the start. That in itself is okay, however another one crops up toward the end of the story and I thought this was a sort of conclusion, but the story continues on. It felt misplaced.
Without giving away specifics I thought it ended in a strange place, with all the build up I expected something big but it just dwindled to a stop quite unexpectedly.
The concept of what a population would do following a collapse of society is an interesting one, and well thought out here, with some interesting ideas of how individuals and groups work through such hardships. Many apocalyptic stories tend to centre around destruction and chaos, zombies, guns, cars that still work years later despite petroleum having a limited life span.
Afterlight is different as it looks at things from a realistic point of view, this is evident in the research the author has done. The characters have flaws, even the good guys don't always get it right, and the bad guys have reasons for their behaviour. It illustrates how some people will strive to help each other and some will act like locusts, consuming and killing.
As with the first book I was dismayed to see the repetitive nature of rape, whether that be actual rape or the intention/implication. I understand it is used to illustrate a point, that of men being dominant over women, using them as objects etc, but it felt forced to the point of "oh, just stop going on and on about rape and docile women and get on with the story!"
Despite these criticisms I thoroughly enjoyed the adventure. Thought provoking subject matter, decent enough characters and locations I could relate to, England, London, East Anglia and so on.
If you want a good read about how people might realistically survive following a collapse then I recommend Afterlight whole-heartedly.
