Under The Gun is the long-awaited sequel to the bestselling novel, Gun Shy, continuing the story of St. Paul Police Officers Dez Reilly and Jaylynn Savage. Picking up just a couple weeks after Gun Shy ended, the sequel finds the two officers adjusting to their relationship, but things start to go downhill when they get dispatched to a double homicide–-Jaylynn's first murder scene. Dez is supportive and protective toward Jay, and things go all right until Dez’s nemesis reports their personal relationship, and their commanding officer restricts them from riding together on patrol. This sets off a chain of events that results in Jaylynn getting wounded, Dez being suspended, and both of them having to face the possibility of life without the other. They face struggles–-separately and together–-that they must work through while truly feeling "under the gun."

St. Paul police officers Dez Reilly and Jaylynn Savage have been working far too hard. When they take off on a camping trip to northern Minnesota with good friends Crystal and Shayna, they expect nothing more than long hikes, romantic wood fires, and plenty of down time.

Jaylynn is taken hostage and must use all her resources to stay alive. Can Dez catch up with the criminals, short-circuit the Russians, and save Jaylynn? It's a race to the finish as author Lori L. Lake uproots Dez and Jaylynn from the romance genre to bring them center stage in her first action-suspense thriller.

With some family complications, a murder of one of their own, and the hunt for a dangerous killer, the girls have their hands full.
