Critical Point

Cas Russell hires out her fighting skills, and her gift for mathematics is just as formidable. She has already halted a secret group that planned to take control of the minds of the entire world. The victory raised new questions, though. Cas has discovered that her earlier life was wiped away on purpose and that her superhuman abilities were built deliberately rather than arising by chance.

The danger is far from over. A bomb specialist has set his sights on Cas and the people she cares about, and the conspiracy that buried her history is resurfacing. As past, present, and future begin to collide, Cas must act fast to protect one of her closest friends.
