Address Unknown

In this new Mercury Carter thriller, the self-styled freelance mailman crisscrosses the Southwest as he juggles his latest delivery with his search for his father's killer and for a missing fitness fanatic.
Mercury Carter's current assignment seems innocuous enough: deliver a JurassiCat—a wildly popular and sought-after toy—to a three-year-old girl in Los Angeles, courtesy of her doting grandparents. The trip out west also gives Carter the chance to detour through Phoenix, Arizona, where the man who orchestrated the death of Carter's father several years ago was recently sighted. As often happens with Carter's assignments, however, things immediately go wrong on both counts and when he finally makes it to LA he finds the little girl and her parents held hostage by armed thugs.
But Carter has never missed a delivery, and he isn't about to start now. While the thugs ransack the home of Kyle and Gwynyth Clemens, Carter finds an unexpected ally in a young man who had come to the house looking for information about his missing half-brother. As Carter struggles to save the family and the young man from both gunfire and the flames of encroaching wildfires, he finds himself dragged into a complex criminal conspiracy. In a pursuit that takes him first to Las Vegas and then northern Arizona, Carter chases down the thugs who disrupted his delivery and follows clues to a rash of disappearances and the cultish wellness community that seems to connect them.
In Address Unknown, Andrew Welsh-Huggins once again delivers the high-stakes action, edge-of-your-seat drama, and quick wit that readers have come to expect from the Mercury Carter series.
