Orphaned twins Grace and Connor Tempest might now be travelling on the same ship, but that doesn't make for plain sailing...

When a textbook pirate attack goes awry, Molucco Wrathe loses one of the most prized members of his crew. It's a wake-up call to Connor and Grace concerning the violence of life aboard a pirate ship.

Cheng Li proffers a tantalizing invite for both twins to experience life at the elite Pirate Academy. There, Connor soon finds his loyalties torn between maverick Captain Wrathe and the all-powerful Pirate Federation.

Grace receives disturbing news from the Vampirate ship and plots a high jeopardy return.

Meanwhile, renegade Vampirate Sidorio stalks the coast - watching and waiting to exact a terrible revenge.
