Seattle is safe, and Spencer Herold and the rest of the Lake Union Adventurers are more than ready for a return to normal. With Count Drizel dead, it seems their troubles are over. But there are still a lot of unanswered questions. Why did Drizel so hate Spencer's family and their friend Luther Baum he was ready to destroy an entire city to get his revenge? And what secret lies in Luther's past? The answers lie in Romania, where Spencer and the gang accompany Luther as he seeks to learn if he's a descendent of the Romanian royal family, and where the mysterious Castle of Bran, once home to the infamous Vlad Dracul--Dracula--hides a dangerous puzzle only Spencer, with the help of his friends, can solve. In this exciting sequel to The Emerald City, Stephen Keeney continues the story of Spencer Herold and his brave band of adventure seekers.
