Revenge of the Mad Scientist by Lara Nance
A steampunk adventure with a hint of romance.
When Lady Arabella Trunkett’s father, the High Lord Minister of Urbannia is kidnapped, all clues point to the mysterious country of Gandiss and the world is thrown into political upheaval.
Arabella is convinced the more sinister nation of Carabarras is to blame, urged on by a mad scientist seeking revenge. So, she sets out on a perilous airship journey across a variety of exotic locales to save him, and halt the potential world war.
But air-pirates, secret assassins and slave traders aren’t her only trials. The fickle hand of fate has made the captain of the only airship available for charter, the man who left her at the altar. For eight years she's wanted nothing more than to see him dead. Now he's her only hope.
