She had vowed never to return to Houston's crime-riddled East End. But Detective Crista Santiago's promotion to the Chicano Squad has put her right back in the violence of the barrio. Determined to transfer out as fast as possible, Crista first has to prove herself by solving a series of drive-by shootings. Crista has only one witness—four-year-old Samantha Del Rio. Protecting Samantha becomes Crista's number one priority, which means staying close to the little girl. And her widower father, Alex. But "staying close" soon changes into becoming part of the family. And the more attached Crista becomes to the girl and her father, the more she's afraid she's lost her edge…and her ability to protect the witness.
