Mystery, murder, and adventure on Mars...

Mars in 1815 is a world of wonders, from the hanging ballrooms of Tharsis City to the air forests of Patagonian Mars, and from the ice caves of Noachis Terra to the Great Wall of Cyclopia, beyond which dinosaurs still roam.

Now the famous jewel thief, the Glass Phantom, has come to Mars, and sixteen-year-old Harriet George's hapless brother-in-law, Bertrand, has been ordered to track him down. Bertrand has never been much of a policeman, and Harriet knows he'll never manage it. When he fails, the whole family will be ruined. So Harriet comes up with a plan: she will capture the Glass Phantom herself. Even if she and Bertrand have to follow her suspects on a perilous dinosaur hunt in the deadly Martian wilderness.

But there are more dangers in the wilderness than just the dinosaurs--and if Harriet can't solve the mystery, she and Bertrand may not make it back from this hunt alive.

"If the plot is great fun, it is the descriptions and world-building that take this book over the top."
- Wendy McLeod MacKnight, author of The Frame Up

"Harriet is a force to be reckoned with ... The plot takes several twists along the way. I enjoyed every one of them and the ending was incredibly satisfying."
- Brandy Painter, Random Musings of a Bibliophile
