I made the huge mistake of reading this as soon as it came out and now I'm desperate for book 2! From the Prologue I was thinking Imhotep The Mummy vibes. It's not Egyptian but it's giving modern witch coven world, meets souls of an ancient world long lost. This has witches, sorcerers, familiars and werewolves. 

Selene is a witch who's magic cost is her memories. Lured to a Tomb, Selene ignores all the warnings and opens it, to her  regret?! - I don't know I NEED book 2!! What did he do?!?!?
