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 in his signature stunning illustrations and direct coloring. Seraphin is a talented but undisciplined student who drives his Latin and physics teacher to the brink of frustration. The boy's thoughts are always centered around the ether, that substance which exists beyond the Earth's atmosphere and is said to 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 final flight.
