Riddled with Clues was finalist for a 2017 New Mexico/Arizona Book Award.

A hospitalized friend gives a puzzling note to Sara Almquist. He received the note signed "Red from Udon Thani" while investigating the movement of drugs from Cuba into the U.S. However, he doesn't know anyone called Red, and the last time he was in Udon Thani was during the Vietnam War. After Sara listens to his rambling tales of all the possibilities, both are attacked. He is left comatose. As she struggles to survive, she questions who to trust: the local cops, her absent best friend, the FBI, or a homeless veteran, who leaves puzzling riddles as clues.


A thriller for thinkers. Sara Almquist is an independent, feisty woman who is not afraid to show her vulnerable side, a role model for our times. —Ilene Schneider, author & rabbi

Riddled with Clues has all the ingredients one needs to read through the night: drugs, murder, the FBI, travel, a romantic relationship, and a little science. A must read. I enjoy reading thrillers, page-turners that draw the reader in and refuse to let go. J.L. Greger's novels meet those criteria and more. As a former university professor in the biological sciences, she adds a new dimension to her stories—education. While reading and enjoying the story, one can learn about interesting aspects of science, such as epidemiology, through the author's character. To make matters even more interesting, the author makes sure she involves scenes from her extensive travel throughout the world. —John Wills, former FBI agent & author

A heroine for her times, Sara is brash and competent because her heart insists she do the right thing—no matter the personal cost.  Deep histories that intersect with Sara's feelings and passions enhance the rich plot line. he juxtaposition of quiet moments that are easily relatable with the action sequences where Sara has to wield a gun and make instantaneous decisions help the readers imagine themselves in her shoes and root for her, especially when it seems that no one else is willing to do so. A fun read. —D.R. Ransdell, author & writing instructor

Riddled with Clues, is an exciting mystery/thriller that will keep you turning the pages. Sara Almquist lives on the edge of intrigue and danger. I'm drawn to independent, beautiful and intelligent women (like) Sara Almquist. Once you've read, this novel, you will want to read I Saw you in Beirut, another Sara Almquist thrilling novel by J. L. Greger. —Walter W. Luce, author, Real Estate Developer
