In this third book in the S.M.A.R.T. Squad series, best friends Izzy Newton, Allie Einstein, Marie Curie, Charlie Darwin, and Gina Carver set out on a mystery-filled outdoor adventure.

Now that Izzy’s finally found her voice in public speaking class and become an ice hockey star, she’s determined to conquer her “dizzy-Izzy-ness” in new situations―including caring for her brand-new braces on an outdoor education overnight and her friends’ good-natured teasing about her friend Trevor. But the forecast for fun turns cloudy when the girls discover their cabin chaperone is none other than Izzy’s tough public-speaking teacher, Ms. Martinez, and their junior counselor is eighth grade mean girl, Maddie Sharpe.
When an innocent exchange of harmless pranks with Maddie takes a turn for the worse, the Squad turns to science to prove their innocence. That’s nothing, though, compared with the terrifying swamp monster haunting their campsite, a catastrophe befalling Ms. Martinez, and a mysterious disaster threatening the future of camp itself.

With their very survival on the line, will science be enough to save the day?
