Three romantic thrillers. Secrets worth killing for.
Continue The Dark Horizon Series by Jordan Fox with the ebook editions of Shadows Orbit, Echoes of the Past and Beneath the Surface, presented as Books 4–6 in reading order.
From falsified orbital records to a clandestine medical programme and a threatened marine reserve, these stories bring dangerous discoveries, relentless pursuit and unexpected intimacy together. Each book is a stand-alone romantic thriller within The Dark Horizon Series.
Book 4: Shadows Orbit
Commander Selene Ward returns from seventeen days aboard a space station with an official account she does not trust. A missing moment in the logs and a crewmate's death lead her to Noah Vale, an analyst fired for questioning orbital tracking data. With a company preparing to erase ninety days of evidence, Selene and Noah head towards a remote desert station, racing to expose the truth as their connection deepens.
Book 5: Echoes of the Past
Nurse Sera Caldwell has rebuilt her life in Hong Kong after mourning Jack Westbrook, who vanished in Macau three years earlier. Then Jack returns with a kill team behind him and proof of a medical programme that breaks people to order. Their escape across the South China Sea offers a second chance at love, but the network pursuing them also has plans for Sera.
Book 6: Beneath the Surface
Marine biologist Naomi Rivers discovers signs of a dangerous secret beneath the Saunivi Marine Reserve. Former soldier Paxton Verrall is hired to protect a scientist who does not want a bodyguard, against enemies who intend to destroy the evidence. With his past closing in and the tide setting their deadline, every night aboard brings them closer and makes the mission harder.
