On Mars, in the distant future, the princess Haydn's arranged marriage cannot save her beloved Republic. Her arch-enemy, the warrior-woman Frane, seeks to make herself Queen while Haydn—the legitimate heir—must flee for her life. A reluctant symbol for those who would restore the monarchy, Haydn is too young and unprepared to assume the throne—but determined to become a great Queen. With a bounty on her head, she will make a perilous journey to the realization that—in order to save her world—she must sacrifice all that she holds dear.

The assassination of Haydn, queen of Mars, draws her son, Sebastian, into a dangerous confrontation with enemies both at home and abroad, including his mother's nemesis, the warrior-woman Frane, who launches a revolt that forces him into exile in the shadow of Olympus Mons, where he prepares to make his final stand. Original.

Princess Clara of Mars must lead the Second Republic to victory against an insane warrior-usurper who wants to take control of the Red Planet, while trying to solve the ancient mysteries of the Old Ones to replenish their air supply before life is no more. Original.
