Operation Meltwater: FreeFlow, a group of internet activists committed to the freedom of information have video evidence of a military atrocity in the Middle East and have chosen Iceland as their HQ while they prepare to unleash their greatest coup on the world's media. On the glacial rim of erupting volcano Eyjafjallajoekull, they christen their endeavour Operation Meltwater. Minutes later, in the steam and mist, one of them is murdered. The list of people Freeflow has antagonized is long - the Chinese government, Israeli military, a German Bank, Italian politicians, even American College Fraternities. Magnus Jonson has a long list of suspects but he's getting precious little help from FreeFlow - for an organization dedicated to the transparency of information, they're a secretive bunch. But they are not the only ones with secrets. Asta, a newly qualified priest, has contacted FreeFlow with information about a scandal in the church. Her involvement with FreeFlow will cost her dear. And with the return of Magnus's brother Ollie to Iceland, the feud that has haunted their family for three generations is about to reignite.
