A young author is invited to an exclusive writer’s retreat that soon descends into a pulse-pounding nightmare . . . 

Fueled by sex, suspense, and the supernatural, The Writing Retreat is a claustrophobic and unhinged, propulsive, closed-door thriller that explores the dark side of female relationships, fame, and the desire to have our stories told. 

"Blending themes of friendship, ambition, creativity and courage, this thrill-packed story brims with secrets, intrigue and murder.  Bartz wrangles tension of the highest order, and executes a fiercely original story with vigour and style." -- Janice Hallet, author of The Twyford Code
