An American citizen born in Paris, Tuck now divides her time between New York City and Maine; she has also lived in Thailand and (during her childhood) Uruguay and Peru. Tuck has stated that "living in other countries has given me a different perspective as a writer. It has heightened my sense of dislocation and rootlessness. ... I think this feeling is reflected in my characters, most of them women whose lives are changed by either a physical displacement or a loss of some kind".
