King Nyx : a novel
(Book)

"Anna Fort wants to be a supportive wife, even if that means accompanying her husband for the winter of 1918 to a remote, frozen island estate so he can finish his book as the guest of an eccentric millionaire. When she learns three girls are missing from a school run by their host, Anna realizes finding them is up to her—even if that means risking her husband’s career, and possibly her life. Her husband’s masterpiece-in-progress features strange meteorological anomalies along with wild speculations about 'facts' he believes scientists hide from the public. Most people think Charles Fort is a crackpot. That’s about to change now that wealthy Claude Arkel is his patron. Yet Anna is sure something’s not right on Prosper Island, though the alarming return of her 'troubles' makes her question her own sanity. Is the figure in the woods really the ghost of her long-lost friend Mary, or a product of her disturbed imagination? Accompanied reluctantly by a fellow guest, the elegant and troubled Stella Bixby, Anna embarks on a dangerous quest to find the missing girls before Arkel finds her—or her own mind unravels." --publisher's website
