Wonder Undercover

In the third book in the critically acclaimed middle-grade series about mystery-solving siblings, Moxie McCoy, fourth grade detective, goes undercover.

Moxie joins the Wonder Scouts to investigate a suspected saboteur in the badge competition. She's never liked the Wonder Scouts, but once she joins the group, Moxie becomes enchanted with earning badges herself!

Meanwhile, someone has broken into Tiddlywhump's Local House of History, and it's up to Moxie's little brother, Milton, to begin his own investigation.

Can this irrepressible detective duo crack two different cases?

Richly illustrated and laugh-out-loud funny Matthew Swanson and Robbi Behr's Wonder Undercover is a must-have for young readers.
