Only One Wave: The Tsunami Effect

“Once again, Jenifer Ruff delivers a heart-pumping thriller! The well-crafted twists surrounding this medical mystery will keep you guessing until the end.” – Audrey J. Cole – USA Today bestselling author

A tsunami strikes a small island in the Pacific Ocean, leaving destruction and 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 the bizarre outbreak. The investigation requires huge leaps of faith and significant acts of courage. What they discover and what they take home with them will change lives forever.

“Only One Wave is a gripping thriller led by captivating characters and an enthralling story that will wash over you, page after page. In this harrowing account of the aftermath of a tsunami, Jenifer Ruff takes you to ground zero of the disaster’s mighty power, wrapping it with a haunting mystery. I loved every minute of it.”—Timothy Browne - USA Today bestselling author
