Freefall

Read Freefall Storyline:

Taking it down a whole 'nother level, Will and Chester journey to the deadly center of the earth in FREEFALL. By the authors of the NYT Bestseller TUNNELS--soon to be a major motion picture!
DEEPER ended with Will and Chester head over heels in FREEFALL-- tumbling through the subterranean Pore with the evil Rebecca twins in hot pursuit, toting phials of the toxic Dominion virus. When, where, will they ever land? Just when the drop seems infinite, the boys hit bottom, and find themselves in a realm of near-zero gravity atop a giant spongy fungus stuffed with flesh-eating spiders. But the true threat lies closer; dangerously close to Will's heart. And above ground, black-clad Styx are sprouting like poison mushrooms, dead-set on spreading their plague!
