Ever since Magnolia Stone’s scientist dad left Shady Pines to find a new job, Maggie’s been stuck in her gramma’s mobile home with her grumpy older brother, Ezra. Now she’s on a mission to put her family back together by winning the Vitaccino Junior Naturalist Merit Award. When Maggie and her best friend, Nate, a wannabe YouTube star and alien conspiracy theorist, scout out a rare bioluminescent fungus, Maggie is certain she’s a shoo-in to win. But after animals around town start sprouting unusual growths and Ezra develops a bluish glow and hacking cough, Maggie wonders what they’ve really stumbled onto. As things in Shady Pines become stranger and more dangerous, and conversations with her dad get complicated, Maggie must use her scientific smarts and Nate’s impressive knowledge of all things spooky to put things back in order and prevent these peculiar glowing mushrooms from taking over their home.
