Blackbringer

Magpie Windwitch is not like other faeries, most of whom live in tranquil seclusion. When she learns that escaped devils are creeping back into the world, she travels all over with her faithful clan of crows, hunting them down. The hunt will take her to the great forest of Dreamdark, where she must unravel the mystery of the worst enemy her folk have ever known. Can one small, determined faerie defeat the forces that threaten to unmake the world?
