What Feasts at Night - T. Kingfisher

Alex Easton, retired soldier, returns in this novella-length sequel to the bestselling What Moves The Dead. When Easton travels to Gallacia as a favor to Miss Potter, they find their home empty, the caretaker dead, and the grounds troubled by a strange, uncanny silence. The locals whisper of a strange breath-stealing being from Gallacian folklore that has taken up residence in Easton's home . . . and in their dreams.
