Following the sudden end of her marriage, Annabelle Beck returns from Melbourne to the sanctuary of her old family home in North Queensland. There, on an archaeological survey, she discovers that the aboriginal field officer, Bo Rennie, knows her from her childhood. Initially intrigued by his old-fashioned manners, she finds herself increasingly captivated by his modest assurance that he holds the key to her future. Eventually she sets out with him on a path of discovery that leads back to her childhood and to the uncovering of family secrets that have lain buried for a generation or more, secrets that will challenge their future together and force them to question whether their love can survive the terrible knowledge they have come to possess.
