Scintilla

Soulfire has always stood out in everything she did. With rainbow hair, golden eyes, and a tongue as sharp as her numerous throwing knives, Soul is best known for her stubborness and her ability to get almost anything done so long as she sets her mind to it.
It's this same stubbornness that nearly got her killed by the Agency who made her into what she is.
Quite literally. She is a Subject, a Synthesized human, made to be more than humankind could ever hope to be.
Now, nearly four years after her Escape, Soul finds herself at the mercy of her creators once more. Only, this time she has a bit of help in the form of her friend Wolf, a wolf-hawk hybrid trained to be a living weapon.
When another Subject escapes from the Facility and Soul takes them in, the world she has worked to build around herself if tumbling down around her ears again. And this time, she isn't sure she'll be able to escape unharmed.
