Michael Morpurgo: Twist of Gold

Sean and Annie have one chance to escape the potato famine in Ireland, and after surviving a shipwreck they land safely in America in search for their father. But their new land is one of hardship and they live in poverty on the streets of Boston. However, their adventure is just beginning. After living aboard a steamboat they then join pioneers traveling across the prairies. Their music and dancing bring joy to all they meet, but their family "torc"--a golden necklace--brings both blessings and curses, and thieves prowl to get hold of it. Annie and Sean must protect their torc as they search for their father: their family's survival depends on it.
