Black Flash — Michael Grant

A small group of strangers living in different towns across America, each with different backgrounds, is chosen. Some have come willingly, while others have been taken in the dark of night. Stark, shadowy terror suddenly invades their dreams and turns their days into living nightmares. While each begins manifesting startling abilities, uncharacteristic behaviors, and frightening visions, they find themselves running from an unseen, unknown enemy. As the clock ticks down and a web of danger surrounds them, threatening to ensnare them forever, a dark memory forces its way back from their haunting pasts, a forgotten truth so horrific they'll fight for their lives to unravel its clues before their dark enemy silences them forever.
