Frankie Sparks uses her inventing skills to trap a leprechaun in this fourth chapter book in the STEM inspired Frankie Sparks, Third-Grade Inventor series.

It’s springtime in Ms. Cupid’s class, and the entire class is excited to build their very own leprechaun traps. Maybe, if they catch one, they will all get the gift of good luck!

And after a few magical clues, it looks like there might be a leprechaun on the loose in Frankie Sparks’s house! Her best friend, Maya, is convinced the leprechaun exists, but Frankie has her doubts—especially when it feels like every trap she designs fails! Will Frankie and Maya find their lucky charm, or figure out how to create some luck all on their own?

"She reads a story about an unlucky leprechaun. Frankie Sparks thinks it's funny, but it's a fairy tale. After all, everyone knows leprechauns aren't real. Unlike Frankie, her best friend, Maya, is convinced that leprechauns exist. In fact, she tells Frankie that there's a leprechaun living in her backyard! So Frankie decides to build her biggest invention yet: a leprechaun trap! And since her trap will be foolproof, it makes sense that the only reason she doesn't catch them is because those magical creatures are just make-believe. But after a few clues, Frankie begins to have her doubts. Will Frankie and Maya discover this lucky charm is real?"--Back cover.
