In a desolate world plagued by vampires known as type Bs, a small society has bloomed within the walls of an ancient abbey in North Yorkshire. That is until civil wars tears through the order. Those who are deemed loyal are spared, the heretics are punished.

One of the heretics escaped and his adopted daughter makes it her mission to find her father. She teams up with three other apprentices and embarks on a treacherous journey through a dead Britain.

Her quest leads to the discovery of enclaves of survivors, some just trying to see tomorrow, and some with more sinister motives. As they navigate through dangerous territories, haunted by both vampires and a lethal pursuer, the heretics wonder...

Can there be peace in this new world?
