Falling Down — David Cole

Half-Hopi computer hacker and Private Investigator Laura Winslow used to work against the law. But when Mexican drug cartels and hired assassins put Southern Arizona in a lethal, strangling grip, Laura sets aside her plans to take time off and begins to work for the police.

Abandoned by her lover, Nathan Brittles, she also seeks serenity in Tohono Chul Park, but is further drawn into chaos when illegal gambling websites for cockfighting appear on the park's computer system.

Soon, a nightmare of desperation, broken trust, and grisly murder stretches her across the borders separating serenity and chaos, love and abandonment, and plunges her into a world of violence and evil far worse than anything she has ever known.
