From Rampant and Ascendant author Diana Peterfreund comes this thrilling companion to For Darkness Shows the Stars, now in paperback. Across a Star-Swept Sea is a romantic science-fiction reimagining of the classic The Scarlet Pimpernel.

Centuries after wars nearly destroyed civilization, the islands of Galatea and Albion stand alone, a paradise where even the Reduction--the devastating brain disorder that sparked the wars--is a distant memory. Yet on Galatea, an uprising against the aristocracy has turned deadly. The revolutionaries' weapon is a drug that damages their enemies' brains, and the only hope is a mysterious spy known as the Wild Poppy. On neighboring Albion, no one suspects that the Wild Poppy is actually famously frivolous teenage aristocrat Persis Blake. Her gossipy flutternotes are encrypted plans, her pampered sea mink is genetically engineered for spying, and her well-publicized new romance with handsome Galatean medic Justen Helo . . . is her most dangerous mission ever.

When Persis discovers that Justen is keeping a secret that could plunge New Pacifica into another dark age, she realizes she's not just risking her heart, she's risking the world she's sworn to protect.
