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.
