Trapped in an unhappy aristocratic marriage, Elinor Coombes sees only lonely days ahead of her. So a present from her father - tickets for the maiden voyage of a huge, luxurious new ship called the Titanic – offers a welcome escape from the cold, controlling atmosphere of her husband’s ancestral home, and some precious time with her little son, Teddy.

When the ship goes down, Elinor realises the disaster has given her a chance to take Teddy and start a new life – but only if they can disappear completely, listed as among the dead. Penniless and using another woman’s name, she has to learn to survive in a world that couldn’t be more different from her own, and keep their secret safe.
