Masters of Mars

Haydn of Mars: Princess Haydn's arranged marriage cannot save her beloved Republic. Her archenemy, the warrior-woman Frane, seeks to make herself queen while Haydn-the rightful heir-must flee for her life, a reluctant symbol for those who would restore the monarchy. Determined to become a great queen, she makes an arduous desert trek into the heart of chaos, where she will find her true love, make unexpected allies-and meet unexpected treachery. Sebastian of Mars: Aided by a trusted regent, Haydn's son, Sebastian, rules the Second Republic. But the sickly young man is unprepared for the crisis brought on by Frane, whose gathering army is transporting a weapon of monstrous power. Taking refuge in the caverns beneath the great Olympus Mons, Sebastian gets ready to make his stand. For there amid its wonders, he uncovers a secret from the ancient past that may save Mars' future.... Queen of Mars: Five years later, as young Princess Clara struggles to hold her world together, Frane resurfaces, determined to wipe the Second Republic and its hard-won technology off the face of Mars. She must be defeated, for more than the freedom of Clara's people is at stake. The Red Planet is dying, its atmosphere slowly leaking away. Clara's scientists need to activate the oxygenation stations the Old Ones left behind-or life on Mars will cease to exist.
