A magical journey that would have taken even Jules Verne's breath away! A father and his son embark on a fantastic adventure in 19th-century Bavaria. A new Alex Alice with the familiar stunning illustrations and direct coloring. Seraphin is a gifted but undisciplined student who drives his Latin and physics teacher to the brink of fury. The boy's thoughts are always centered around the ether, that substance which is said to exist beyond the Earth's atmosphere and could enable previously unimaginable projects outside the globe. Even Seraphin's mother shared this passion and met her end when she ascended to over 13,000 meters in a hot air balloon. His initially skeptical father is swayed when he receives an anonymous letter from someone claiming to possess his wife's notes that she took on her last flight.
