When Protecting His Body Means Risking Her Heart

Step into the danger zone with Guardian of Secrets, the eighth riveting installment in Jordan Fox's Dark Horizon Series. This adrenaline-charged romantic thriller flips the script on protection, proving that sometimes the strongest shields are the ones we least expect.

Harper Knight is the security industry's best-kept secret—an elite bodyguard whose uncompromising focus and lethal skills have saved countless whistleblowers and activists from certain death. Her reputation is flawless, her boundaries impenetrable. Until Oliver Kensington.

Born into one of the world's most powerful dynasties, Oliver has discovered a horrifying truth: his family's vast empire is secretly funding the Dark Horizon, a shadowy network manipulating global politics for profit. When he decides to expose everything, the price on his head makes him the target of the very family that raised him. With nowhere else to turn, he hires Harper—never expecting that his bodyguard would be a steely-eyed woman who challenges everything he thought he knew about strength and sacrifice.

As they navigate Dubai's dazzling skyscrapers and secluded luxury estates, assassination attempts come from every direction—even from within Oliver's inner circle. With each narrow escape, the professional boundaries between protector and client blur into a dangerous attraction neither can afford. Harper's job is to keep Oliver alive, not fall for him. But as they uncover layers of conspiracy that reach into the highest echelons of power, she realizes that guarding his body might mean sacrificing her heart.
