I ended up really enjoying this, but it did take a while to get into it. The main story is about an Irish woman's expedition to Namibia to seek her mother and an aquifer (she's a hydrologist), sponsored by the Chinese authorities. There is a lot more to it than this and it is part adventure story and part a study of the importance of water both in a country where it is desperately short, Namibia, and where there is an abudance, Ireland. Also a study of a country riven by foreign involvement.
The writing is interesting with lots of metaphors throughout, some quite convoluted, which a takes a bit of getting used to, but it's worth it. The voice changes regularly as well and certain phrases come out as if thought by a particular character, rather than the third person narrator.
The characters were convincing and well drawn and the settings were excellent - especially the desert. There is also plenty of stuff about aquifers, if that's your thing!!
For me, once it got going, it was an exciting adventure, beautifully written, with a lot more in besides.
