Alchemy Of Murder - Rex Baron

She is the descendant of the most powerful magical bloodline in Europe.

Yet Elizabeth finds herself in the thrall of the dangerous but dazzling son of Helen.
Backed by his ancestors, with years of magical training, the only thing that can satisfy his lust for power comes at an immense cost.
A cost he intends for Elizabeth to pay.
Having spent a lifetime denying her power, Elizabeth must step up and tap into her untrained resources if she is to have any chance of escaping.
Or surrender her soul.

Alchemy of Murder is volume six of the spellbinding eight-part historical fantasy drama Hexe, which tracks the dark magical exploits of four women over the course of a century. It is a sweeping tale of obsessive love, witchcraft and retribution, in which each of these extraordinary women discover their unique abilities, and struggle to come to terms with their own secret gifts of power.
