The Light Between Oceans

Great War veteran Tom Sherbourne seeks a quiet job to recover mentally. The initially temporary post of lighthouse keeper at Janus Rock, a desolate island off Western Australia, becomes permanent as the incumbent dies. In the nearest town, which delivers his monthly provisions by boat, he meets and weds Isabel Graysmark, from a wealthy family. Their happiness is hurt by her miscarriages, so when a lifeboat strands with a dead man and a live baby, she persuades him to bury the former and pass the latter for their second stillborn, with no official mention. Later he learns it's the bigots-chased German husband of the richest landowner Septimus Potts' disowned daughter Hannah Roennfeldt and their daughter Grace, which they are raising as Lucy. Tom needs to come clean, at least anonymously announce the child lives, but Isabel is obsessed with motherhood. Tom is arrested but refuses to recant his lie covering her role despite the likelihood that he will be hanged.
