Only Wrong Once
2017
A sinister experiment outside Aleppo. Two mysterious deaths: one in LA, one in Boston, each with the same horrific symptoms. In Los Angeles, FBI counterterrorism agent Quinn Traynor receives an urgent call from CDC agent, Madeline Hamilton. She’s discovered the first victim of a lethal, unfamiliar virus. Their joint investigation uncovers an imminent bio-terror attack and their only hope is to identify the terrorists carrying the disease. With just two days remaining before it’s too late, the FBI and the CDC race to prevent a pandemic. The ensuing nightmare will hit closer to home than they ever anticipated and one of them will pay an unimaginable price for protecting the country. "Jenifer Ruff does an outstanding job of weaving personal stories in the lives of the characters amidst the action. This book will keep you glued to the pages from beginning to end, wondering what will happen next." – Susan Mills Wilson, author of Hunt for Redemption "The story is riveting, the characters are well-drawn, and the plot moves at break-neck speed.

Only One Cure
2020
The President's son is dying. Terrorists claim to have the only cure. When a private plane whisks CDC epidemiologist Madeline Hamilton to Washington D.C. for an urgent medical symposium, she knows something significant is underway—but she doesn’t expect to face the most disturbing medical mystery of her career. A debilitating neurological toxin has stricken the children of several political families, and one of them is the son of U.S. President Anna Moreland. With the lives of children on the line, Madeline assembles a team of medical experts. The investigation takes a horrifying turn when she starts receiving communications from the terrorists, who want to engage in a deadly political game. Desperate to find the perpetrators and a cure, the White House recruits FBI antiterror specialist Quinn Traynor to run a parallel investigation. As the teenagers start dying and the answers seem no closer, Madeline and Quinn fight to prevail before President Moreland is forced to make an impossible choice: give in to the terrorists’ demands or let her only child succumb to an agonizing death.

Only One Wave
2021
A tsunami strikes a small island in the Pacific Ocean, leaving destruction and utter madness in its wake. After the natural disaster, CDC epidemiologist Dr. Madeline Hamilton and her fiancé, FBI operative Quinn Traynor, go to Nalowale Island to investigate a deadly outbreak of unknown origin. Victims become aggressive and irrational, suffering from insomnia, hallucinations, and eventual death. But not everyone cooperates with the agents’ efforts to save lives. Devon Wheeler’s fortune depends on completing construction of the Azure Cove Resort. He’s hiding something, and he’ll do whatever it takes to open the luxury complex on time, even if it means concealing critical information related to the outbreak. When all communications to and from the island shut down and the wave of illness climbs toward a calamitous crash, Madeline uncovers something terrifying…and impossible. Under quarantine conditions and without the help of modern equipment, Madeline and Quinn must make sense of a bizarre outbreak that will forever change the world’s understanding of viral pathogens. With time running out, their knowledge may come at an incredible price.
