The Coven Heir (The Coven Series Book 2)

The Dark never dies.
One year after The Company of Clan Munro was defeated, things in the UK Coven are settling down, and also beginning to be shaken up.
The Princess, Harley Sinclair, is building her potion business and planning a wedding to James Quigley, while still taking lessons from her father, the Coven King.
Her younger half-brother, Nick Smith, is moving to London with three friends ... including Roger Ainsley, the son of the former leader of the Dark.
When a mysterious stranger appears back from the dead, his words of warning of another Dark Clan rising might change Nick and Harley's lives forever.
There's a deathwitch in the Coven, and she has her sights set on the Princess.
