Book II in the Vinland Trilogy. Ragnarök, the twilight of the gods, has begun. The Jötunn overthrow Asgard, home of the Norse gods, forcing the exodus of its ruler Odin, and members of the house of Æsir. When Loki descends to Vinland to claim power for his Jötunn progeny, Odin must follow to ensure the Vinlanders' destiny is fulfilled. Meanwhile, Thorfinn is working to honour his agreement with the First Nations people and leave Vinland, but an assassin's attack sends his wife Gudrid into premature labour, and when she regains consciousness, she's horror-stricken to find baby Snorri missing. A mysterious visitor urges them to journey to Leif's southern settlement and into the caves at the Bay of Fundy in Nova Scotia Canada, to seek Snorri-and to stop Loki from acquiring the Gram, the sword of power. There, Freydis betrays her kin to seize power, forcing the dwarf Tostig from her brother's camp. Tostig flees for his life-but his fate has already been written in the great sagas. The path to the end is paved with blood and sacrifice, and only the gods know what the final outcome will be.
