When 13-year-old Eric Parrish comes across glowing mushrooms in the woods behind his house, hes sure theres a scientific explanation. But when they start encroaching on the town—covering the football field and popping up from beneath the floorboards—Eric knows somethings seriously wrong. Not that much else is going right: his parents are fighting, his little brother Brian is a little pill, and hes 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 towns 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.
