One house, two children, 137 years between them.

In 1776, orphaned but wealthy Sophie Rutledge lives a life of privilege in a fine Georgian house in Dublin, quite unaware that her murder is being plotted.

In 1907, Mickser Lawless and his impoverished family occupy the same house, now a tenement, Mick's father is dying and his family will be thrown into the street to starve.

Then they both see ghosts. Sophie is frightened by the phantom of a ragged, starving boy. Mickser is terrified by the apparition of a beautifully dressed young woman.

This is the tale of a boy and girl who have absolutely nothing in common but a house -- and danger. They cannot help themselves but they can help each other, if they are able to overcome their fear. But time is running out. On Christmas Eve -- 1776 and 1907 -- events come to a shocking conclusion. Nineteen Railway Street explores the link that connects two different worlds and two remarkable young people on the brink of maturity.
