Ines of My Soul by Isabel Allende

Born into a poor family in Spain, Inés, a seamstress, finds herself condemned to a life of hard work without reward or hope for the future. It is the sixteenth century, the beginning of the Spanish conquest of the Americas, and when her shiftless husband disappears to the New World, Inés uses the opportunity to search for him as an excuse to flee her stifling homeland and seek adventure.
