When a body is found strung up on the crane of an offshore oil refinery on the Alaskan coast, FBI Special Agent is called in to investigate the suspected work of a serial killer. Against the stormy seas and brutal elements, she soon realizes there’s more to this bleak landscape than meets the eye.

Only Once: A Sadie Price FBI Suspense Thriller is book 4 in a chilling new series by mystery and thriller author Rylie Dark, which begins with Only Murder (book 1).

Special Agent Sadie Price, a 29-year-old rising star in the FBI’s BAU unit, stuns her colleagues by requesting reassignment to the FBI’s remote Alaskan field office. Back in her home state, a place she vowed she would never return, Sadie, running from a secret in her recent past and back into her old one, finds herself facing her demons—including her sister’s unsolved murder—while assigned to hunt down a new serial killer.

What seems like a straightforward case quickly embroils Sadie in an international territorial dispute, bringing in multiple agencies and countries and further complicating her investigation.

After a rabbit hole of dead ends, Sadie uses her brilliant mind to think of something no one else has—and another body—and a shocking twist—may just catch her off guard.

But in this stormy wilderness, in the thick of winter, does Sadie have any hope of finding him before it’s too late?

An action-packed audiobook, the Sadie Price series is a riveting crime thriller, jammed with suspense, surprises and twists and turns that you won’t see coming. It will have you fall in love with a brilliant and scarred new character, while challenging you, amidst a barren landscape, to solve an impenetrable crime.

Books 5 and 6—Only Spite and Only Madness—are also available.
