Flight-714 II: Forbidden Power.. Flight-714, #2

On the isolated, high-tech shores of No Island, the social hierarchy is as lethal as the magic that governs it. Lebreau Villiers, a ruthless tactician with ambition that dwarfs the island's formidable defenses, has finally begun to consolidate her power. But in a world where loyalty is bought with blood and maintained through manipulation, the "peace" she has brokered is a fragile one. Deep beneath the campus lies a forbidden labyrinth...a graveyard of abandoned projects, undesirable acquisitions, and weapons of unimaginable destruction.
When Emily Heartfield, a sniper haunted by her own abusive past and the shadow of her former leader, reveals the location of the unit's ultimate target, Lebreau orchestrates a daring mission into the dark.
