A murder on the edge of an erupting volcano... Magnus Jonson searches for the truth in the third instalment of the Fire and Ice Quartet. FreeFlow, a group of internet activists, christen Operation MELTWATER on the glacial rim of volcano Eyjafjallajökull. Minutes later, one of them is murdered. The list of people FreeFlow has antagonized is long - the Chinese government, Israeli military, a German Bank, even American College Fraternities. Magnus Jonson has a long list of suspects but he's getting little help from FreeFlow - for an organization dedicated to the transparency of information, they're a secretive bunch.
