A billion-dollar superstore has its sights set on a small Minnesota river town for its next outlet.

The blasts are meant to inflict maximum damage and utmost fear. They do. Virgil Flowers has been enlisted to find out who's behind the dangerous acts, but the answer he uncovers may be the biggest shock of all.
