Jacob, Callum and Zane are desperate to rescue Mr. Barnaby from the eternal realm and possible possession by one of the time vampires. That means traveling through a portal once more… something that didn't go all that well the first time. Unfortunately for Jacob and all of his friends, the only key to Mr. Barnaby's saviour is in the haunted lighthouse far out in the rough waters of Pembroke Bay. A place where legend says those who venture never come back. What's more, not only is the town of Pembroke Eve at stake, but the lives of every person on the planet hang in the balance as the eternals put into place their plan to take over the human realm. Yes, the eternals want power, but they're pissed off as well, having lost hope of taking over the dragon realm, thanks to Jacob and his friends. Meanwhile, Aloysius and Suzy must hold the fort at home, looking after both the General store and the Food Emporium. After all, a shipment of noodles at a bargain price has just hit town and who else will hold back the crowd in Mr. Barnaby's absence while Jacob, Callum and Zane go rescue him? Sure, Jacob may be a king and the younger brother of powerful dragon, but can he and those he loves survive long enough in the lighthouse to discover the key they need? Or will they become the next victims of the curse of the lighthouse? The gang are in for the fight of their lives this time…with unexpected results.
