It’s an opportunity she can’t refuse. The woman before her tried…

Freya Miller needs a miracle. In the fallout of her husband’s betrayal, she’s about to lose her family home, and with it the security she craves for her five-year-old daughter, Skye. Adrift and alone, she’s on the verge of despair until a chance meeting with the charismatic Dr Marsden changes everything. He’s seeking a new tenant for a shockingly affordable flat in a fashionable area of London.

Adder House sounds too good to be true… But Freya really can’t afford to be cynical, and Dr Marsden is adamant she and Skye will be a perfect fit with the other residents.

But Adder House has secrets. Even behind a locked front door, Freya feels as if she’s being watched: objects moving, unfamiliar smells, the blinking light of a concealed camera… and it’s not long before she begins to suspect that her dream home is hiding a nightmarish reality. Was it really chance that led her here—or something unthinkably dark?

As the truth about Adder House starts to unravel, can Freya and Skye get out—or will they be locked in forever?
