Though happy to be back on her home planet of Mars, Arabella's peace is shattered when she receives distressing news. Her long-absent fiancé Capt. Prakash Singh, commander of the Honorable Mars Company airship Diana, has been taken as a prisoner of war on Venus, the very planet where the exiled Napoleon has fled.
Desperate to rescue Singh any way she can, Arabella pays off the gambling debts of a rakish privateer captain in order to arrange passage on his vessel. But when they're captured by a French squadron and taken to Venus, Arabella finds herself reunited with Singh, as a captive in the same brutal prison-camp.
In a spacefaring adventure filled with interplanetary espionage, cosmic combat, and mind-blowing inventions, Arabella finds herself torn between two very different—yet ultimately courageous—men. Together they plot a daring conspiracy to expose Napoleon's dangerous plan: the building of a secret weapon that would make the French emperor virtually unstoppable.
"Arabella embarks on another entertaining quest in an imaginative setting that combines 19th-century seafaring with pulp-style space adventure."—Publishers Weekly
