Alex, a struggling writer, is thrilled. Upon arrival, they discover they must complete an entire novel from scratch, and the best one will receive a seven-figure publishing deal. Alex's long-extinguished dream now seems within reach.

But then the women begin to die. Trapped, terrified yet still desperately writing, it is clear there is more than a publishing deal at stake at Blackbriar Estate. Alex must confront her own demons - and finish her novel - to save herself.

This unhinged, propulsive, claustrophobic closed-door thriller will pull you in and spit you out.
