"I love you. Of course I do. But we haven't any choice in the matter, do we? If our little boy's health, even his survival, is at stake, we have to do whatever it takes."

New York City, 1928: Ellen and Lucas Lyman have made a heart-wrenching decision to leave their beloved Amherst Island behind in search of a new life. The island was once the home of their hearts: where they had met as children, become friends, and over time found love.

But New York City was calling, and it was everything they'd hoped for and more. With Lucas making money on the stock market, and Ellen finding fulfilment as a mother, at first they are happy raising their family, together, in the most exciting city in the world.

Until their beloved son, Jamie, becomes perilously ill, and Ellen is given an impossible choice. With Lucas unable to leave his job, it is down to her to take Jamie to a place he might recover even if it means making the journey across America without him.

Ellen knows what she must do. What every mother would do to save their child. Even if it takes her further away from the man she loves - and every place she has called home - than ever before.
