The Writing Retreat by Julia Bartz

Five attendees are selected for a month-long writing retreat at the remote estate of Roza Vallo, the controversial high priestess of feminist horror. 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 - and finish her novel - to save herself.
