Blood Curse - The Priory Chronicles, #1

Over three centuries ago the Church began a personal vendetta against witches at Salem. Historians tells us that very few people who were accused actually died but history was wrong! I would know, I was there, and trust me the Church and its representatives burnt people who were accused of being witches with all the enthusiasm of a carnivore at an all you can eat barbeque. As a priest, albeit not a very good one, I was discovered having an intimate relationship with a married woman but no one doubted my word when to save myself from embarrassment I renounced my lover as a witch who had seduced me.
Unfortunately, what I didn't know is that my accusation was actually true and as she burnt at the stake she cursed me with her dying breath sending me straight to Hell, which for fallen priests was certainly no holiday camp!Ten years later with a demon attached to his soul, Jonah Spenser is finally ejected from Hell to wander the world as a broken man until he comes to the attention of "The Priory", an organisation created to counter the threat of the supernatural.
For over three centuries his hell-born appendage gives him a unique insight into a shadowy world until a mission goes wrong and he is cast aside. Now Jonah is back and tasked with searching for a lost manuscript that may be the key to a war that has raged since civilization began. The only problem is he's not the only one looking and Jonah is forced to deal with vampires, werewolves as well as his psychotic witch ex-lover who still holds a grudge and who has returned from the dead with vengeance in mind. All in all, just another abnormal day.
