When a violent Mexican drug cartel joins forces with a powerful, local gang, Det. Becker Gray is caught in the middle of a series of gruesome murders and grisly attacks. As the violence, betrayals, and pain escalate, revenge fuels the fires that bring a war to the city streets.

------------------------------------------

Detective Becker Gray doesn't have many close people in his life. There's his partner, Jeffrey Parker, and Morgan Beringer, the mayor's wife. In his own emotionally-detached way, he treasures both. Yet, when Morgan and her husband are murdered, he doesn't know what to make of his sense of loss and he doesn't lean on Parker for friendship.

Besides, there's no time to do so anyway because there are more dead bodies stacking up than the city can handle. First, a fire fighter is gunned down in broad daylight. Then eight members of a powerful, local gang are killed. Gray discovers all these murders are connected by ties to a Mexican drug cartel, police corruption, and even state attorneys tampering with cases. For Gray, though, these connections only serve as distractions to his main goal of finding Morgan's killer.

Even his only remaining friendship is a distraction. Parker is instead simply another tool Gray uses to corner the murderer.

Gray puts his life and career -- and that of his partner Jeffrey Parker -- on the line in THE WALLS. He faces his most savage nemesis in this exciting, quick, and breath-catching novel that will leave his professional life and the police department in tatters and upheaval.
