Alex Alice's Castle in the Stars: A Frenchman on Mars is the fourth volume in a lavishly illustrated graphic novel series set in a world where space exploration began during the Victorian era. As Seraphin, Hans, and Sophie make their descent to the Mars surface—with stowaway Loïc and the wicked Gudden in tow—they’re prepared for danger. But with its gravity-defying rain and giant carnivorous beasts, Mars is even more treacherous than they expected. When Seraphin suddenly finds himself separated from his friends and alone in the Martian wilderness, he must trust a mysterious shape-shifting creature to guide him back to safety. But this creature has an agenda of their own.

What if man journeyed into space in 1869, not 1969? In The Knights of Mars, the third volume in this breath-taking fantasy graphic novel series, Alex Alice draws on Jules Verne and nineteenth-century romanticism to create a watercolor world of adventure and wonder to enchant adults and younger readers alike. When Seraphin, Hans, and Sophie returned from their voyage to the moon, they didn't come home empty-handed-they brought with them aetherite, a miraculous substance that defies gravity! To keep their secret safe from the Prussians, the trio lives in hiding on a remote island in Brittany. Meanwhile, Seraphin's father has founded the International Society of Aether, a group of scientists dedicated to the peaceful pursuit of space exploration. But on the eve of their inaugural meeting, he vanishes without a trace! The Knights of Aether's last hope lies in a daring rescue of King Ludwig and Professor Dulac. They will find them on the farthest outskirts of the Prussian empire-the planet Mars!
