Fatal Fallout

This is an Apple Books audiobook narrated by a digital voice based on a human narrator.
Torn between duty and desire, two strangers must risk all for love 

Nuclear physicist Dr. Claire Fleming has one rule: never get close to anyone. But when her colleague is murdered and she's targeted next, she must place all her trust in FBI agent Thomas Kincannon. Soon Claire forgets her tenet as she fantasizes about Thomas's touch. 

Thomas is wildly attracted to Claire. But his life and his job are too complicated for any romantic entanglements. Despite this, they share a mind-blowing kiss, and there's no turning back. When Thomas's niece is abducted, the stakes become dangerously higher as Claire insists he trade her for the child. Somehow, Thomas must find a way to rescue his family and protect the woman who let her protective walls down just for him.
