Montgomery and the Case of the Golden Key

In 2008 Chicago, in the Southside community of Washington Park, Montgomery “Monty” Carver had hopes for the best summer ever! Unfortunately, things aren’t going as planned. Monty is struggling to prove to his parents that he’s old enough to be without adult supervision—especially after a very embarrassing incident with a metal detector. Man!
So when Monty finds a golden key in Old Lady Jenkins’s sunflowers, he decides he’s going to unravel the key’s mystery all by himself, thank you very much. No parents allowed. Besides, he’s ten years old now, and he’s mastered the perfectly round ’fro! (It takes a protractor, you see.)
Soon Monty’s hunt to determine the origin of the key leads him to discover the rich history—like famous Black jockeys!—of his Chicago community, which has been speculating its future since one of their residents, Barack Obama, is running for president and the Olympics might come to town in 2016.
On top of all that speculating, there are rumors going around that a ghost is hanging out behind their apartment building, and that Monty’s elementary school may have to close.
So much to solve! Should the Olympics come to Washington Park? What happens if his school closes? Is there really a ghost? And where, oh where, did the key come from anyway? Monty is determined to find out.
"An engaging novel drawing strength from its rich narrative voice and celebrating Black historical luminaries."—Kirkus Reviews
