Seraphin and his crew, which includes the King of Bavaria, have barely escaped the treacherous chamberlain with their lives. They are now stowaways on the magnificent aethership, but their respite is short-lived. To save the king's throne and prove his sanity, they must push the aethership even farther—out of the sky . . . and into the stars!

In the exquisitely illustrated Castle in the Stars series, Alex Alice delivers a fantastical adventure set in a world where man journeyed into space in 1869, not 1969, and he marries this compelling high-concept premise with intricate, breathtaking art.
