Rosie Revere is no stranger to flops and fails, kerfuffles and catastrophes. After all, engineering is all about perseverance! But this time, Rosie has a really important project to tackle—one that feels much bigger than herself.
 
Rosie’s beloved Aunt Rose and her friends, the Raucous Riveters—a group of fun-loving gals who built airplanes during World War II—need help inventing something new. And Rosie is just the engineer for the job!
 
After one flop . . . then another . . . and another . . . Rosie starts to lose hope. But thanks to some help from her fellow Questioneers Iggy Peck and Ada Twist, Rosie gets the job done. And, along with the Riveters, she rediscovers the meaning of home.

Cover of Iggy Peck and the Mysterious Mansion
Iggy Peck is an architect at his very core: When he’s not making houses out of food, his head is up in the clouds, dreaming of design. So he’s totally blown away when Ada Twist’s 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 something’s not quite right . . . Everyone says the house is haunted, and it seems that a number of priceless antiques—which were supposed to help Aunt Bernice pay for the house’s upkeep—have gone missing. If they can’t find those antiques, Aunt Bernice might lose the house forever. It will take all of Iggy’s knowledge of architecture and the help of the other Questioneers—Rosie Revere, Ada Twist, and Sofia Valdez—to solve the mystery and find the treasure!
