There's a new ship of vampirates roaming the seas, leaving a trail of fear and devastation in its wake. When a high-profile pirate is slain, the Pirate Federation takes decisive action and begins training up a ship of dedicated vampire hunters. The team will be led by newly appointed Captain, Cheng Li and will include pirate prodigy Connor Tempest. Meanwhile, Connor's twin sister Grace enjoys a bittersweet reunion with their mother. Sally Tempest...

While Connor faces trouble in the form of an obnoxious new crewmate, Grace, his twin sister, seeks out a vampirate guru who might be able to heal their dear friend Lorcan's blindness.

When twins Connor and Grace's ship is wrecked in a storm and Connor is rescued by pirates, he believes that Grace has been taken aboard the mythical Vampirate's ship, and he is determined to find her.

Evil Sidorio continues to expand his empire across the oceans, but as he faces growing opposition from both the Pirate Federation and the vampirate realm, twins Grace and Connor Tempest are caught in the conflict.

Connor must decide whether a pirate education by sea or by school is the most logical.
