Ever since fabulously wealthy Malcolm Doran walked into her life and swept her off her feet, fledgling architect Jane Boyle’s world has become an absolute fairy tale. When he proposes with a stunning 5-carat diamond to seal the deal, Jane can’t believe her incredible fortune and decides to leave her Paris-based job and make a new start with Malcolm in New York.

But when Malcolm introduces Jane to the esteemed Doran clan, one of the most feared and revered families of the New York City upper crust, Jane’s fairy tale takes a darker turn. Soon everything she thought she knew about the world and herself is upended, and Jane is left to struggle with newfound magical abilities and the threat of those who will stop at nothing to get them. Bringing together the dual fascinations of high society and black magic, 666 Park Avenue is a story of a young woman’s discovery and survival when her mother-in-law to-be turns out to be a horrible, grasping witch…literally.
