Iggy Peck is an architect at his very core: When heâs not making houses out of food, his head is up in the clouds, dreaming of design. So heâs totally blown away when Ada Twistâs Aunt Bernice inherits an old house from ice-cream mogul Herbert Sherbert that is filled with countless rooms from all his favorite architectural periods. But somethingâs not quite right...
Everyone says the house is haunted, and it seems that a number of priceless antiquesâwhich were supposed to help Aunt Bernice pay for the houseâs upkeepâhave gone missing. If they canât find those antiques, Aunt Bernice might lose the house forever. It will take all of Iggyâs knowledge of architecture and the help of the other QuestioneersâRosie Revere, Ada Twist, and Sofia Valdezâto solve the mystery and find the treasure!
