In one devastating night, Etta Spencer loses everything she knows and loves. Thrust into an unfamiliar world by a stranger with a dangerous agenda, Etta is certain of only one thing: she has travelled not just miles but years from home.

Nicholas Carter is content with his life at sea, free from the Ironwoods - a powerful family in the Colonies - and the servitude he's known at their hands. But with the arrival of an unusual passenger on his ship comes the insistent pull of the past that he can't escape and the family that won't let him go. Now the Ironwoods are searching for a stolen object of untold value, one they believe only Etta, his passenger, can find.

Together, Etta and Nicholas embark on a perilous journey across centuries and continents, piecing together clues left behind by the traveller who will do anything to keep the object out of the Ironwoods' grasp. But as they get closer to their target, treacherous forces threaten to separate Etta not only from Nicholas but from her path home forever.
