The year is 1919 and the place New York City. A one-armed WWI veteran spends the night inside the mansion of a wealthy hoarder and lives to tell about it--from a room in Bellevue Hospital's psychiatric ward.  Miles Trenowyth returns from the War to End All Wars a changed man, but soon resumes his career as a civil attorney. One of his clients, Noah Langley, is under threat of eviction from his boarded-up and booby-trapped four-story Harlem mansion stuffed to the ceilings with untold tons of bizarre "collections" that the hoarder has acquired over a lifetime.  Miles finds himself trapped inside the mansion, along with Noah and Miss Cora Buxton, a comely social worker intent on ministering to the hoarder, and over the course of one night, he confronts a brand of terror worse than anything faced on the battlefields of Europe . . . "With stunning attention to historical detail, and characters that practically jump off the page, Christopherson delivers a blood-soaked thriller you won't soon forget."   -- Jude Hardin, author of KEY DEATH "Christopherson has penned a deliciously wicked tribute to the glory days of Gothic horror."   -- Mark Carver, author of THE AGE OF APOLLYON FORTRESS OF EPHEMERA is a new thriller from the author of CRACK-UP and THE PROPHET MOTIVE.  Praise for Eric Christopherson's earlier novels: CRACK-UP: A PSYCHOLOGICAL THRILLER Best Mystery Novel, Red Adept Annual Indie Awards"A fast-paced excellently crafted thriller, gripping from start to finish.
