Shock Wave (Virgil Flowers Series‪)‬

The superstore chain PyeMart has its sights set on a Minnesota river town, but two very angry groups want to stop it. The first bomb goes off on the top floor of PyeMart's headquarters. The second one explodes at the construction site itself. Who's behind the bombs, and how far will they go? It's Virgil Flowers's job to find out… before more people get killed.
