The Missing American

By Kwei Quartey

As the title suggests, an American goes missing during a visit to the country to meet a woman he met online.

By Dean Koontz

The prolific Dean Koontz is always up to something, and his fans know that he’s quite the dog lover. So, it makes sense that he would write a novel that is essentially a love letter to human-canine companionship. Kipp is a devoted dog that has a secret power—the ability to communicate without speaking. Woody Bookman is an 11-year-old that hasn’t spoken since his father died. When unspoken evil creeps on the horizon for both Woody and his mother, it’s up to their devoted dog, Kipp, to help.

First Cut

By Judy Melinek & T.J. Mitchell

This book gets right what other medical thrillers get wrong. The science is spot-on, and the star of the novel, medical examiner Jessie Teska, is truly memorable. When she is transferred from Los Angeles to San Francisco, she is struck by the rampant disorganization in her new office. Her first case, a possible overdose, might have been an open-and-shut case, but that would be too easy. Teska is strong-willed and the sort of character that carries even the most mundane moments well.

The Sun Down Motel

By Simone St. James

Sometimes a story’s location has so much charm, intrigue, and charisma, it becomes a character all its own. This is the case with the eponymous roadside motel in Simone St. James’s The Sun Down Motel. A woman named Carly is searching for her aunt, Viv Delany, who went missing before she was born while working a night shift at the Sun Down Motel. As it turns out, Carly’s fascination with the motel wasn’t by chance. It wanted her there all along.

St. James takes her time turning up the volume on the supernatural edge of the thriller so well, you’ll find yourself basking in the setting, holding back the frenetic turning of the pages just to enjoy Sun Down a little while longer.
