Gone the Next by Ben Rehder (Kindle)

Meet Roy Ballard, freelance videographer with a knack for catching insurance cheats. He's working a routine case, complete with hours of tedious surveillance, when he sees something that shakes him to the core. There, with the subject, is a little blond girl wearing a pink top and denim shorts—the same outfit worn by Tracy Turner, a six-year-old abducted the day before. When the police are skeptical of Ballard's report—and with his history, who can blame them?—it's the beginning of the most important case of his life.
