In centuries past, a brother and sister are orphaned in an isolated outport cove on Newfoundland's northern coastline. Their home is a stretch of rocky shore governed by the feral ocean and a relentless pendulum of abundance and murderous scarcity. Still children with only the barest notion of the outside world, they have nothing but their family's boat and the little knowledge passed on haphazardly by their mother and father to help them survive. Muddling through the severe round of the seasons it is their fierce loyalty to each other that motivates and sustains them. But as seasons pass and they wade deeper into the mystery of their own natures, even that loyalty will be tested.
