Nothing can dampen social standing quite like spiritual possession and a vengeful dead sister.

1859. Emma Collins is heartbroken. The man she loves has just ripped out her heart and stomped all over it with his polished oxfords.

But things are about to get worse.

Old secrets she thought she'd buried begin resurfacing. Nightmarish hallucinations of Emma's deceased sister bring forth her own guilt, and from these visions emerges Morgana, an ancient and powerful being.

Morgana has only one desire: Emma's swift and brutal death.

With her grandmother's help, Emma must find a way to destroy Morgana before she loses her life, and perhaps worse, her place in London society. Joining them on their quest is an odd family friend with deep secrets and an American who is too handsome for his own good.

When Emma learns the truth behind her sister's ghost and Morgana's deadly ambitions, she must make a decision that will not only alter the future of her family, but humanity itself.
