'A dark mystery in a dark age brought vividly to life' - Robert Fabbri

Everyone loves a family reunion.

He can deny it all he likes, but everyone knows Viking warlord Unnthor Reginsson brought home a great chest of gold when he retired from the longboats and settled down with Hildigunnur in a remote valley. Now, in the summer of 970, adopted daughter Helga is awaiting the arrival of her unknown siblings: dark, dangerous Karl, lithe, clever Jorunn, gentle Aslak, henpecked by his shrewish wife, and the giant Bjorn, made bitter by Volund, his idiot son.

And they're coming with darkness in their hearts.

The siblings gather, bad blood simmers and old feuds resurface as Unnthor's heirs make their moves on the old man's treasure - until one morning Helga is awakened by screams. Blood has been shed: kin has been slain.

No one confesses, but all the clues point to one person - who cannot possibly be the murderer, at least in Helga's eyes. But if she's going to save the innocent from the axe and prevent more bloodshed, she's got to solve the mystery - fast . . .

Lies. Manipulation. Murder. There's nothing quite like family . . .
