How could a bar-fight change the lives of everyone aboard the Silver Dawn? Or for that matter: how could the frail (and mysterious) Miss Malikarv do the same? But toss in Rocket Hampster and his sex-crazed lover, a stowaway and a peg-legged man and you soon get Chaos!

A leisurely cruise turns into a nightmare as Captain Zak's fabulous airship runs foul of saboteurs, storms, steam-pirates, pterodactyls and mad scientists. Then, when all seems settled, who should turn up but an 'aquainance' from Book One with evil plans of her own; plans that could wreak havoc on all of Varste!
