Its 20,000 inhabitants lived in the shadow of Vesuvius, which they believed was nothing more than a mountain. But Vesuvius was a volcano. And on the morning of August 24, A.D. 79, Vesuvius began to erupt. Within twenty-four hours, the entire city of Pompeii—and many of its citizens—had been utterly annihilated.It was not until hundreds of years later that Pompeii saw daylight again, as archaeological excavations began to unearth what had been buried under layers of volcanic rubble. Digging crews expected to find buildings and jewelry and other treasures, but they found something unexpected, too: the imprints of lost Pompeiians, their deaths captured as if by photographic images in volcanic ash.

     In Elkhorn Slough, an inlet on the California coast, seagrass grows healthy and strong in the shallow water. This healthy seagrass baffled marine biologist Brent Hughes. The scientist expected this estuary to be overrun with algae, causing the seagrass to die. Why was the seagrass thriving? As Brent investigated, signs pointed to an unexpected player helping to keep the seagrass healthy: sea otters! What do these top predators have to do with an aquatic grass at the opposite end of the food chain? Brent's discovery gave scientists insight into the delicate balance of ecosystems. Follow science in action as Brent conducts the research that led to this major discovery.

    Temple Grandin and her brilliant invention: the hug machine.As a young girl, Temple Grandin loved folding paper kites, making obstacle courses, and building lean-tos. But she really didn’t like hugs. Temple wanted to be held—but to her, hugs felt like being stuffed inside the scratchiest sock in the world; like a tidal wave of dentist drills, sandpaper, and awful cologne, coming at her all at once.

    They were tiny men, dressed all in green. Nobody but Frances saw them, so her cousin Elsie painted paper fairies and took photographs of them "dancing" around Frances to make the grown-ups stop teasing. The girls promised each other they would never, ever tell that the photos weren’t real. But how were Frances and Elsie supposed to know that their photographs would fall into the hands of Sir Arthur Conan Doyle? And who would have dreamed that the man who created the famous detective Sherlock Holmes believed ardently in fairies— and wanted very much to see one? Mary Losure presents this enthralling true story as a fanciful narrative featuring the original Cottingley fairy photos and previously unpublished drawings and images from the family’s archives.
