Clay, Alayna & friends return in the second instalment of the humanity's edge trilogy, this time around we also meet two new groups of survivors - Samantha & Malcolm, one of which acts decidedly not in the interests of Clay & friends. This contact builds throughout the instalment as Clay tries to trace his family.

Overall, it was a pretty decent book, certainly entertaining, however I found it a bit odd that they would drink water from a toilet that's been in contact with, you know, a toilet, rather than open the cistern and drink clean fresh water that hasn't. They also get a flat tyre on a wheel they intend to throw out but rather than just driving and ruining the wheel and getting where they want to go they instead walk providing a plot point - a minor niggle yes, however I did find it a bit odd with all the talk of protecting each other and surviving that they wouldn't just drive on a flat.

Asides for that, the trilogy's narrative definitely improves in this book. ( )
