The creators of Brains On!, the award-winning science podcast for kids, introduce readers to a fact-filled and humorous look at the weird and wonderful world of microbes! It's show-and-tell day, and Dominique can't wait to introduce her awesome pets to the class. They're more helpful than dogs, cuddlier than gerbils, and way smarter than lizards. They're her...MICRO-PETS! As Dominique takes her classmates on a tour through her microbiome, they'll meet some face mites, hang with feet fungi, and visit the fart factory-powered by bacteria in her intestines!

Bored and hot on a lazy summer day, three young children watch as birds, bees, and butterflies zoom past them, over their fence, and into their neighbor's mysterious yard. But why are there no birds or bugs in their yard? Why does the neighbor's yard glow with fireflies at night, while their yard is dark? Well, the kids are determined to find out...and maybe make some changes to bring a little wilderness to their backyard.
