What parents need to know

Parents need to know that Iggy Peck and the Mysterious Mansion focuses on the star of the picture book Iggy Peck, Architect and melds friendship, humor, and young Iggy's obsessive interest in architecture into a delightful, ghostly mystery. This third book in the Questioneers series from author Andrea Beaty features the further adventures of a diverse group of inquisitive, goodhearted kids trying to figure out what's really going on at the town's rundown mansion. Historical and architectural information is sprinkled throughout, and the appendix has pages of information about Ida B. Wells, the science of making ice cream, why cats' eyes can be different colors, and the difference between art nouveau and art deco styles. The reference to the impact of the 1918 flu epidemic is especially notable in the time of the COVID-19 pandemic.

What's the story?

When Ada Twist's Aunt Bernice inherits a rundown mansion from the town's famous recluse in IGGY PECK AND THE MYSTERIOUS MANSION, she plans to use the priceless antiques inside to pay for renovations. But there are two problems: The house is supposedly haunted, and the antiques are nowhere to be found. Iggy Peck is fascinated with architecture and is sure that the mansion holds the key to the mystery. Iggy, Ada, and fellow Questioneers Rosie Revere and Sofia Valdez will have to use their wits and talents to solve the mystery before Aunt Bernice has to sell the mansion.

Is it any good?

The simple kindness among the friends sets the tone for a fun, adventurous mystery, and the kids' curiosity leads to academic information being seamlessly sprinkled throughout. Younger readers will find the vocabulary challenging ("blueprint," "antique," "suffragist"), but there are lots of contextual clues to help. The friends in Iggy Peck and the Mysterious Mansion are diverse in background and interests, and they complement each other perfectly: researching, inventing, and examining the things that fascinate them most, all with an infectious enthusiasm. The mansion's quirks bring architecture to life, and the characters continue the warmth, positive lessons, and engrossing stories of the Questioneers series.
