CIA agent Lucy Donovan has been trained to force her way into situations where most others would flee. Although she has survived plenty of dangerous missions, the last one was so upsetting that she developed post-traumatic stress disorder and fears it will prevent her from doing the job she loves. To make matters even worse, on her last assignment her former college boyfriend, Navy SEAL Gus Atwater, had to come to her rescue.

Now, ten months later, Lucy and Gus must work undercover as the married couple Luna and Gustavo Aguiler, who unfortunately for them must speak only Spanish. Their assignment is to work with U.N. representatives in Colombia in order to free two American captives. The work will entail hiking through the jungle, sleeping on the ground, traipsing through dangerous waters, and dealing with other dangers such as malaria, snakes, landmines, and terrorists.

As Lucy and Gus reconnect during the assignment, old feelings come into play. Soon they are dreaming of a honeymoon on a romantic sunny beach—or at least one of them is.  First they need to survive the deadly ordeal in which they find themselves, and then they both must confront some unresolved issues.

From Melton’s continuing series of Navy SEAL heroes, the title Show No Fear refers to the work at hand and the developing relationship between Lucy and Gus. Although mosquitoes, ticks, and jungle rot don’t sound very romantic, the author manages to squeeze in some love and lust in between the military action and terrorist activities. The romantic subplot is easy to predict—as most romances are—but the main story about rescuing the captives will keep readers excitedly turning pages. Melton doesn’t delve too deeply into gory details about violent acts, or love acts either for that matter, but she pays plenty of attention to developing a riveting story of action and suspense.
