Black Side of the Green Line - Halcyon Siege by David B. Hayze

When Agent Jim Popavich and his cadre of ethnically diverse U.S. Border Patrol Agents are abruptly ordered to surrender their guns and badges, the boundaries between ally and enemy quickly shift as they navigate through a brutal world where maniacal shadow corporations, second-rate drug cartels, bungling smugglers, and illegal aliens turned cold-blooded mercenaries will do anything for a piece of the American Dream…and the American continent.
