In one devastating night, violin prodigy 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 traveled not just miles, but years from home. And she's inherited a legacy she knows nothing about from a family whose existence she's never heard of. Until now.
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 so easily. Now the Ironwoods are searching for a stolen object of untold value, one they believe only Etta, his passenger, can find. In order to protect her, Nick must ensure she brings it back to them-whether she wants to or not.
Together, Etta and Nicholas embark on a perilous journey across centuries and continents, piecing together clues left behind by the traveler who will do anything to keep the object out of the Ironwoods' grasp. But as they get closer to the truth of their search, and the deadly game the Ironwoods are playing, treacherous forces threaten to separate Etta not only from Nicholas but from her path home forever.
Etta Spencer didn't know she was a traveler until the day she emerged both miles and years from her home. Now, robbed of the powerful object that was her only hope of saving her mother, Etta finds herself stranded once more, cut off from Nicholas-the eighteenth century privateer she loves-and her natural time.
When Etta inadvertently stumbles into the heart of the Thorns, the renegade travelers who stole the astrolabe from her, she vows to finish what she started and destroy the astrolabe once and for all. Instead, she's blindsided by a bombshell revelation from their leader, Henry Hemlock: he is her father. Suddenly questioning everything she's been fighting for, Etta must choose a path, one that could transform her future.
Still devastated by Etta's disappearance, Nicholas has enlisted the unlikely help of Sophia Ironwood and a cheeky mercenary-for-hire to track both her and the missing astrolabe down. But as the tremors of change to the timeline grow stronger and the stakes for recovering the astrolabe mount, they discover an ancient power far more frightening than the rival travelers currently locked in a battle for control... a power that threatens to eradicate the timeline altogether.
