From Emily Calandrelli-Emmy-nominated host of Xploration Outer Space, correspondent on Bill Nye Saves the World, and graduate of MIT-comes the fifth novel in a fun illustrated chapter book series about an eight-year-old girl with a knack for science, math, and solving mysteries with technology.

Third grader and inventor extraordinaire Ada Lace is on spring break. But it's just a little less relaxing than she'd imagined. Nina is beside herself with excitement about meeting her favorite artist and enlists Ada and Mr. Peebles's coding-whiz nephew to help revamp her online portfolio.

When Nina finally meets Miroir, he snubs her, and her confidence is shaken-but not enough to miss the art show opening. While there, Ada spots a suspiciously familiar painting that may mean Miroir isn't the original he claims to be.

Will the friends be able to reveal the artist's true nature, before he fools someone else?
