A young Viking warrior's body has lain undisturbed beneath Isdal glacier for centuries, his hand grasping a golden arrowhead incised with runes. When Skuli and Jack disturb the corpse, Jack experiences an immediate connection through time with the young Viking - and feels the power emanating from the arrowhead.
A story of violence, raiding and treachery between brothers unfolds as an ancient curse is released. As the night gets wilder and the town's inhabitants behaviour becomes increasingly strange, Jack and Skuli realise they alone can lay old ghosts to rest, and lift the curse by performing a Viking ship burial.
With its complex, well-defined characters and vivid setting, Arrowhead's narrative also shares much of the same dark driving power that drives Viking mythology, in this thrilling time-slip novel.
