Critical Point

The explosions have never been bigger as math-genius mercenary Cas Russell returns in the next blockbuster adventure from S. L. Huang, Critical Point, a breakout science fiction thriller series for fans of John Scalzi and Greg Rucka. Cas Russell has stopped a shadow organization from brainwashing the world and discovered her past was deliberately erased and her superhuman abilities deliberately created. And that's just the start: when a demolitions expert targets Cas and her friends, and the hidden conspiracy behind Cas's past starts to reappear, the past, present, and future collide in a race to save one of her dearest friends.
