Laura is a nurse in a paediatric unit. On long, quiet shifts, she and her colleagues, clad in their different shades of blue, care for sick babies, handling their exquisitely frangible bodies, carefully calibrating the mysterious machines that keep them alive. Laura may be burned out. Her hands have been raw from washing as long as she can remember. When she sleeps, she dreams of water; when she wakes, she finds herself lying next to a man who doesn’t love her any more. And there is a strange figure dancing in the corner of her vision, always just beyond her reach.
