Call of the phoenix

This breathtaking steampunk adventure series introduces an alternative 19th century of giant airships soaring through the skies above the English Channel, fantastical, steam-powered automata, aerial steam carriages, floating cities and a new kind of secret agent. As Napoleon's airborne invasion of England begins, Lady Arabella and the Sky Sisters face a new enemy, the Equestrians: a group of ruthless, masked fighters mounted on powerful mechanical horses.

The future looks bleak as Arabella and Miles, her trusty steam-powered sidekick, battle to save the British Empire from a fleet of gigantic airships and a terrifying army of iron centaurs.
