Audrey's Door is a chilling read about cults and architecture reminiscent of Rosemary's Baby. Audrey Lucas runs from a painful childhood, a bi-polar mother, a demanding job, and a fiance, right into the welcoming arms of the Breviary, an old Manhattan apartment building with a questionable history of tenant suicides and murders. But the rent is cheap and the deal too good to pass up.
The incestuous, elderly, trust fund baby tenants of the Breviary need a door to the Other Side built, and through new rental trial and error they're closer than ever to seeing it happen. The tenant before Audrey got close, but her door wasn't finished because of a tragedy that struck her and her children. The elderly clan who run the Breviary are creepy, watchful, and "selfish as the day is long" to quote Minnie Castevet from Rosemary's Baby.
Slowly Audrey begins losing touch with reality and wakes feeling battered and bruised. Her breakdown is brought on by fevered and exhausting dreams about building a door...to where? And what wants to come through it? Is she working too hard? Is it her OCD? As her past and present fuse together, what or whom will she sacrifice to give they tenants what they desire?
Through the smallest of details Sarah Langan builds upon the layers of even her minor characters, making Audrey's Door believable and horrifying. Even Audrey's boyfriend Saraub and his mother are treated as fully-fleshed characters and not mere tools to move the plot along. This book has made me a Langan fan.
