Running Dark — Jamie Freveletti

From internationally bestselling author Jamie Freveletti comes a riveting new thriller featuring brilliant biochemist Emma Caldridge, except this time there's nowhere to run. . . .
Emma Caldridge is on mile thirty-six of the fifty-five-mile Comrades ultramarathon in South Africa when a roadside car bomb explodes. Dazed and disoriented, she regains consciousness after the blast to find a man standing over her with a white plastic injector. She feels the prick of a needle and the rush of medication under her skin, but before she can make a sound, the man is gone.

Shaken by the event and unsure of what substance was pumped into her, Emma calls the one person who can help her figure things out: Edward Banner of the security company Darkview. But Banner has his hands full with another emergency: Somali pirates in the Gulf of Aden have attacked a cruise ship, and Darkview has been hired to assist with the rescue.

However, according to intelligence sources, the ship is carrying cargo far more valuable than wealthy passengers--something that could be a new weapon of unknown origin. Suspecting the weapon may be chemical in nature, Banner asks Emma to infiltrate the ship and use her professional expertise to identify it. Emma knows it's a risky job, one that she might not survive. But when she learns that special agent Cameron Sumner--a man who has saved her life in the past--is among the hostages, nothing will stop her from getting onboard, no matter what the cost.
