Lilac is miserable.
Ignored by her callous parents and bullied by her peers at school, the young girl finds herself quite alone. Nobody wants to talk to her save Aislinn, her bubbly classmate, and Mrs Khoury, the school's councillor - but, even then, Lilac suspects they only do so out of pity.
The only person Lilac feels able to trust is her older brother, Jesse, but she has not seen him in what seems an eternity. He moved away from their small Cornish village two months prior to attend a university in the bustling capital of the country, London.
Lilac misses Jesse so intensely she can think of nothing else. As the days pass, she becomes more and more fixated upon him, until her obsession threatens to consume her.
When she learns that her brother will be coming back home for Christmas, at long last, she can't contain her excitement...
But her brother, as she soon discovers, is not alone. A strange woman has ensnared his heart in his absence, and Lilac finds her already fragile mental state unraveling faster still. She knows she must free her beloved brother from the grip of this wicked enchantress, no matter the cost, if she is ever to be happy again - but just how far is she willing to go...?
