Light Between Oceans

What would you do for the 'want' of a child?   What would you do for the  'love' of a child?  Isabel  ' wants' a child so much and has suffered several miscarriages, so is it  a 'gift from God' that Lucy comes into her life?  What about the guilt that her husband, Tom, carries with him, not only from the war but concerning Lucy. What would you do when there is no 'right ' answer.    Good read and thought provoking.
