"A whirlwind journey, filled with heart-wrenching tension and sinister twists. This is the kind of dark romance you thirst for!" - Alexandra Christo, internationally bestselling 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 and guard 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 uncover a startling truth in the form of Ravel Severin: a rogue vespertine who reveals the monsters have secrets of their own. Ravel promises the help she needs - but or a heavy price. Vespertine magic requires blood, and if Everline wants Ravel to guide her across the dangerous moorland, she will have to allow him 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 . . .
