🚀 She came to rescue a crewmate. Now she’s Earth’s most wanted—and Mars’s only hope.

In Losing Mars—Book Three of the Red Galleon series—this thrilling young adult sci-fi adventure takes readers deep into a future where minds can be copied, bodies can be stolen, and loyalty might be the only thing left to trust.

Martian pilot Jessamyn Jaarda doesn’t like Kipper—but she doesn’t need to. When her crewmate is marked for Earth’s sinister consciousness transfer program, Jess risks everything on a covert mission to bring her home.

While Jess slips through the shadows of Earth’s desert settlements, an imposter moves into their Martian sanctuary. Under orders from the ruthless Chancellor Lucca Brezhnaya, the Terran infiltrator—Gaspar—has one job: capture Jessamyn and Pavel before they can expose the truth.

But Pavel suspects the danger too late. To prevent a breach in Mars’s fragile defenses, he destroys Jess’s only ship home—forcing her to decide whether loyalty is worth trusting the very people who’ve betrayed her before.

🌌 Readers will experience:

  • A covert rescue mission with tense, planet-scale stakes
  • Classic Golden Age sci-fi tropes with modern depth
  • A strong female lead driven by principle and fierce loyalty
