Hiding in Plain Sight

She'd always thought she just had a knack for weaponry. But Tenten soon learns that there's more to her than anyone thought. This discovery will lead her to a mysterious weapon, a not-so-underground war, and an odd band of rogues. And before she knows it, she'll be forced to make an impossible choice. Sometimes, ignorance really is bliss. AU. Rated for blood, swearing, etc.
