Finally got round to finishing this tonight. I enjoyed it. I thought it was going to go down the psycho-thriller road, but I actually thought the eco-thriller approach was refreshing. For me at least, as it's the first one i've read. There's enough psycho-thrillers out there.
I found it really unnerving as I could see it happening soon. And when I was reading about all the disasters that bloody volcano went off! Totally freaked me out lol
