Grasping at Gravity

Sometimes you find yourself at the end of your tether.
A ring of reverse half gravity encircles the globe, the result of a cataclysmic event that occurred 500 years in the past. Tallow has been performing the duties of a scout for years and all he knows is that life is difficult at the base of the swath.

He travels along the edges of the limen, a threshold separating the earth-bound from the sky-bound - a border the tether tribes have never dared to cross. One misstep could cost him his life.
While scouting for resources, Tallow encounters something he's never seen before, a woman, one with knowledge about his people that she shouldn't have - and a warning. Her allegations couldn't possibly be true, they lived in different worlds. Her people couldn't cross over to learn about his people any more than the tribes could cross over to learn about hers. The problem is, he can't get her out of his mind, and soon learns that a dangerous lie underpins everything he has ever known.
