Erna and Alfreda Anderson were two real passengers that traveled third class on the Titanic, but nothing is known about them, except that Erna survived, and Alfreda did not. The author of this book has written a novel that imagines who Erna and Alfreda Anderson were, why they were on the Titanic, and how Erna made it out of the tragedy alive when Alfreda, her relative, did not. The Erna of this book is a ten-year-old dreamer living in the Swedish countryside, often at odds with her realistic, sixteen-year-old sister Alfreda. Their father has been in America for several years, and sends tickets for the family to join them. But their mother must remain behind, so the sisters set off without her, arguing along the way. They board the Titanic in England, and they're on their way. Along the way, they finally manage to become friends. And how Erna survives, and her sister does not, happens in a tragic plot twist that was painful to read and had me nearly in tears. I highly reccomend this book. It goes along well with Voyage on the Great Titanic, from the Dear America series.
