A Complete Four-Book Series by Miles North

The Saltmere Subjects

Four books. One programme. From a haunted Scottish coast to the polar night, nine experimental subjects fight to decide whether they are weapons, property, or people.

On the cliffs above a struggling fishing village, grief-stricken prodigy Isla Marsh thinks a prestigious fellowship at Saltmere University is her escape. Instead, she is drafted into a covert enhancement programme run by corporate giant Blackwood Marine and the ruthless Dr Helena Voss – a decades-old experiment that rewrites her biology, binds her to a handful of other subjects through a psychic ocean-borne bond, and quietly erases anyone who doesn’t survive the process.

Across four novels, Isla and her fractured cohort are pushed from test subjects to fugitives, rescuers, and, finally, insurgents – through covert infiltrations, polar rescues, and a final siege on the place where it all began.

The Saltmere Subjects is a character-driven science thriller series about consent, weaponised science, and found family under extreme pressure – where the monsters are human, the sea never stops calling, and the last subject standing has to decide what kind of person she is willing to be to bring everyone home.
