Spark (The Elements, #3)

Four extraordinary teens, each cursed with a corrupted gift from one of the four elements: Water, Fire, Earth, and Wind.
After discovering that SanCorp was continuing with their human experimentation, the group of four escaped in a blaze of fire. Refusing to be turned into weapons and refusing to turn a blind eye on the death and torture that SanCorp was guilty of, they have decided to take down the company as a whole. They will not run. They will not hide. They will no longer be the hunted. They will become the hunter.
Spark is Eve's story. Earth is more than just the dirt under our feet. It encompasses all the energy around us. It can be beautiful in the flowers and the trees it helps to create, or the animals and the life it brings forth. But it can also be destructive and ugly, and it can kill. Now that Eve and the group have something more than just themselves to protect, Eve may become the weapon SanCorp wanted all along. Only this time, the weapon will be focused on them.
