Skilled in two vernaculars, children shoulder basic and more complicated verbal exchanges for non-English speaking adults. Readers hear, through children's own words, what it means be "in the middle" or the "keys to communication" that adults otherwise would lack. Drawing from ethnographic data and research in three immigrant communities, Marjorie Faulstich Orellana's study expands the definition of child labor by assessing children's roles as translators as part of a cost equation in an era of global restructuring and considers how sociocultural learning and development is shaped as a result of children's contributions as translators.
