Summoning

A fast-moving Gothic thriller, sinister and evocative, calling on many elements of the supernatural as well as contemporary issues, as experienced through the eyes of a feisty heroine without a recorded identity.
Ankerita, a Tudor noblewoman released from her tomb after half a millennium of disturbed sleep, is desperately trying to stay one step ahead of the evil organisation that needs her for her unique blood, and the demons still trying to reclaim her soul.
Her best friend is dying, but that there is a chance the friend can be cured if Ankerita can complete the 'Summoning' using a number of lost treasures, hidden long ago by a sorcerer from Celtic legend.
The ritual has to be evoked on a specific night, when five planets are aligned for the first time since she died, but her pursuers are ever present, and the Summoning comes with a price. Hers will be the ultimate sacrifice, if the invocation fails.
