An Al Quinn Novel: Book 6 Trouble might be gaining on you. When Al agrees to help Fergie find the missing son of one of their long-ago high school classmates, they head off to a ranch in the valley, where some wide open spaces still remain in Southeast Texas. Al is okay with following Fergie's lead in the case, for a change, and even with riding horses. But what he doesn't expect is for the trail to lead them to encounter one of America's most violent gangs, the Mara Salvatrucha. The MS-13 members are vicious, tattooed career criminals who have devoted their lives to machetes and guns. And this bunch is gearing up to wage war with other gangs-fighting, maiming, killing, and dying over their turfs, colors, and hand signs. Heaven help anyone in their way. But to do their job, Fergie and Al end up squarely in the gang's path.
