Priest - a post-apocalyptic sci-fi thriller set in an alternate world - one ravaged by centuries of war between man and vampires. The story revolves around a priest who disobeys church law to track down the vampires who kidnapped his niece. Maggie Q is of course amazing.
"The deep and resonant plot that serves as the anchor for her actions, and for those of her long-lost childhood love, Tengo Kawana, a young writer whose movements and thoughts we observe in alternating chapters, plays out under a sky with two moons and unfolds at a leisurely pace."
The Witches by Roald Dahl. Roald Dahl played a major part in my childhood, and The Witches was one of my favourites by him. It scared me, and I appreciated having a children's book that didn't flinch from fear!
