This is the kind of dark romance you thirst for!" - Alexandra Christo, author of To Kill A Kingdom.Sink your teeth into a bloodstained tale of a girl torn between her vows and her heart, where falling in love may be the deepest sin of all. . .Everline Blackthorn has devoted her life to the wardens - a fierce sect who wield arcane magic to guard their community against vampiric monsters known as the vespertine.When a strangely human vespertine is killed on their borders, and a series of unsettling events follow, Everline disobeys orders and uncovers a startling truth in the form of Ravel Severin: a rogue vespertine who reveals that monsters have secrets of their own.Everline's own magic has failed to appear, and she is feeling both outcast from her own community and powerfully drawn across the vespertine-fllled moors. As Ravel also needs Everline as cover to return home, he promises to use his magic to ensure safe passage for them both for the treacherous journey, but at a heavy price: vespertine magic requires blood, and Everline will have to allow Ravel to feed from her.But it's a sin for a warden to feed a vespertine - let alone love one. As Everline and Ravel travel across the desolate moorland, their fractured, temporary trust in each other is put thrillingly to the test and Everline realises the question isn't only whether she will survive the journey - but if she does, if she will ever be the same again . . .
