From the New York Times bestselling author of The Darkest Minds trilogy and Lore.

I’ve been orphaned by my time.
My future is gone.

Etta Spencer didn’t know she was a traveller 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 travellers who stole the astrolabe from her, she vows to destroy it once and for all.

Devastated by Etta’s disappearance, Nicholas has enlisted the unlikely help of Sophia Ironwood and a cheeky mercenary-for-hire to track her down. But after a deadly mistake derails their search, they discover an ancient power that threatens to eradicate the timeline as they know it.

In this stunning conclusion to the Passenger series, #1 New York Times bestselling author Alexandra Bracken charts a fascinating course through time that will captivate readers.
