Lilith Saintcrow does not write happy characters living pleasant lives in easygoing situations containing happily ever after endings. Her characters tend to be damaged, flawed, angry yet spirited and keep themselves going almost in spite of themselves. Her villains are never straightforward, typical villians either - they are definitely evil {they are hellbreed, after all} and yet will sometimes be caught doing good deeds even if it's all for the wrong reasons.
That being said, Heaven's Spite is another very strong installment in a dark urban fantasy series. There is a strong horror aspect within many of Saintcrow's novels and this is no exception. People are getting ripped up and murdered left and right. There are evildoers, middle of the road people, desperately poor clawing their way through the day, the obscenely rich, and to balance things out there are the Hunters - the characters that are fighting a seemingly losing battle against the bad ones - the hellbreed and hellspawn that are preying on the innocent and not so innocent. These characters, Jill Kismet is the main character, never give up. They aren't angelic, they aren't wonderfully well behaved people; they are flawed and damaged but they are doing their best.
Saintcrow's writing keeps me interested. Her books are very dark, her characters are rarely happy, things frequently seem hopeless or doomed and yet she keeps things alive and vibrant with her action scenes, the constant atmospheric touches {i.e., the tinkling of the charms in the hunter's hair, the throbbing of the demon mark on Jill's wrist that changes with the situation and mood of Perry, the smells and sounds described throughout the book, etc}, the angry yet dark humor, thoughts and the unexpected snarky comments of Jill and crew. The very things that I've seen complaints about are the very things that, for me, add character and atmosphere to Saintcrow's novels. Not many writers can pull this type of thing off - the combination of despair and triumph, the building of scenes and moods with words, the feeling that you can not only picture in your mind what's going on, but you can hear the different sound, the charms and feel the sensations throughout the book, with every different scene - but Lilith Saintcrow sure can. Added to the atmospheric touches - even though her characters, plots, subplots and situations can seem bleak, hopeless or doomed, the fact that her characters are fighting against seemingly impossible odds and never ever give up makes me want to keep reading to see what is going to happen next - see if they make it
Lilith Saintcrow's Heaven's Spite was an extremely enjoyable read for me - the action, horror, suspense, fight scenes; the dialogue, utter lack of info dumps {Halleliujiah!}, the spirit of characters, the flawed and damaged characters, dark humor and twisted plots all combined into a hell of a read for me. The Jill Kismet series is the type of book/series that I like to keep around so I can relive the stories - in this case, the world of Jill Kismet and her hellbreed adversaries. The next - and final - book in the series is Angel Town.
