The Lights Go Out in Lychford

Be careful what you wish for...
Paul Cornell's The Lights Go Out in Lychford continues the award-nominated Witches of Lychford series, described by Seanan McGuire as "Beautifully written, perfectly cruel and ultimately kind."
The borders of Lychford are crumbling. Other realities threaten to seep into the otherwise quiet village, and the resident wise woman is struggling to remain wise. The local magic shop owner and the local priest are having troubles of their own.
And a mysterious stranger is on hand to offer a solution to everyone's problems. No cost, no strings (she says).
But as everyone knows, free wishes from strangers rarely come without a price...
