After four harrowing years on the Western Front‚ Tom Sherbourne returns to Australia and takes a job as lighthouse keeper on Janus Rock. To this isolated island‚ Tom brings a young‚ bold‚ and loving wife‚ Isabel. Years later‚ after two miscarriages and one stillbirth‚ the grieving Isabel hears a baby’s cries on the wind. A boat has washed up carrying a dead man and a living baby. Isabel persuades Tom to keep this “gift from God‚” and we are swept into their story.
