When 13-year-old Eric Parrish comes across glowing mushrooms in the woods behind his house, he's sure there's a scientific explanation. But when they start encroaching on the town--covering the football field and popping up from beneath the floorboards--Eric knows something's seriously wrong. Not that much else is going right: his parents are fighting; his little brother, Brian, is a little pill; and he's had a falling-out with his football team--over a pig.
Then a runaway girl from a nearby boarding school warns Eric that the fungus could portend the town's doom and leave it in rubble--just like the village that inexplicably disappeared in the exact same spot over 200 years ago. Eric, Brian, and Mandy set out to solve a very old mystery and save the town of Tanglewood.
