House of Killers Books in Order

The House of Killers trilogy is a fast-moving espionage story centered on Neva, an assassin raised and conditioned by a covert organization called the Network. She has been taught to follow orders, bury emotion, and treat every target as a job. That carefully built control starts to fail when one assignment makes her confront what the Network has done to her.

Neva is not written as a simple hero or villain. She is skilled, watchful, and used to surviving alone, but the series keeps testing the small pieces of conscience and memory that break through her training. Her growing need for answers turns a professional killer into a fugitive with enemies on every side.

Her path crosses with Michael Kensington, an MI5 agent working with the Archive, a secretive unit investigating connected executions and cases with espionage links. Michael knows Neva may be dangerous, yet he is drawn into her orbit. Trust is never easy between them, and their personal connection adds another problem to every investigation.

London and other European settings give the books a contemporary spy-thriller feel, while the Network supplies the larger threat. It is more than an employer: it has shaped children into assets and reaches into places its former operatives cannot easily escape. As the trilogy moves from The House of Killers to Kill or Die and Kill a Spy, old allegiances fracture and the danger spreads beyond any one mission.

Expect pursuit scenes, surveillance, violent confrontations, hidden histories, and people who may be lying even when they sound convincing. The books move through alternating viewpoints, especially Neva's and Michael's, so readers can see how differently they judge the same risks. Romance sits alongside the action, but it never removes the central question of whether either person can safely rely on the other.

This is a series for readers who want brisk, high-stakes spy fiction with a morally complicated lead. Start with The House of Killers, since Neva's background, Michael's investigation, and the Network's reach all build across the three books.
