Trapped in an earthquake with a half-dozen panicked kids, she fears the worst. When billionaire Roy Brandt leverages his mysterious nanite technology to rescue them, she’s both grateful and intrigued. Though he’s adamant about using the Dust to improve life, not destroy it, corporate raiders and the military have other ideas. $0.99 on Kindle.
