In this alternate reality, a select few are born with the power to harness the weather (air and water), or fire, or Earth: wardens. They control the world by controlling the natural forces, taking the bite out of storms that would otherwise decimate cities, helping the land regrow after wildfires and so on. Their power is augmented by djinn who do their bidding, but they're not invincible.
Joanne Baldwin is a Weather Warden, and she's just had a Demon Mark forced onto her. Running for her life, she tracks down the only person she can think of to help her: Lewis, the most powerful warden and the only person in history with power in all five elements. A threat to the Association of Wardens himself, he took three djinn with him when he broke out: Joanne's only hope is that he'll give her a djinn who'll take the Mark from her before it destroys her.
But Lewis isn't home, and the djinn he left to guard it tells her to go to Oklahoma. With a viscious storm following her and someone of immense ability trying to skewer her with lightening bolts, Jo finds that friends aren't who they seem and neither are new allies - including the cute hitchhiker, David.
Ok, plus points - it's the only way to do this:
1. Jo: great narrator, great protagonist, fiesty, strong, flippant, quick-witted, independent, interesting, flawed, hopeful, down-to-earth, compassionate, tough - not so slow to piece things together that she gets frustrating (especially considering we learn as she learns); not so smart-mouthed that she's annoying; not so powerful and other-worldly that she's unrealistic and unrelatable - in short, she's a sympathetic character with charisma.
2. the concept: fantastic idea, very well executed. I especially appreciate that humans aren't controlling nature with no adverse side-effects or anything like that. It's subtle work, and they have to take into account things like how a storm cleared up in one place will only rebound with greater force elsewhere. Cause and effect, that kind of thing. Throughout the story the sense of a volatile, unpredictable energy force (i.e. nature) creates a tense, dangerous backdrop for a tense, sometimes dangerous plot. I didn't even mind the personification of storms - in fact, it would have felt wrong if they weren't personified.
3. the djinn: not usually a trope that I go out of my way for, but I've come across djinni in two other fantasy trilogies that I can think of: Chaz Brenchley's Outremer trilogy and Jonathan Stroud's Barthimaeus trilogy (both of which I recommend, especially the latter). I greatly enjoyed how they were used here, though I didn't realise that djinn would even be in this book, but it's a great extra dimension to include and helps create a more complex, intricate world.
4. narrative/prose: since it's written in first-person, it comes with Jo's personality and she really drives the story. I read it quickly because she's a bit of a storm herself. Things are always happening, and she's frank, not at all whiny, doesn't overthink things, and has an eye for sexy men. Nice. Especially David. Double nice. Oh he was a real sweetie. Where was I? Oh, right. The structure is tight, and neatly goes back and forth in time at just the right time, slowly revealing all the angles in the story. It begins in the middle, at least that's how it feels, and there's little extrapolation or background, you just get swept up in it and figure it out as you go (not that it's complicated, it's just new).
5. the ending: I had no idea how it was going to end - it seemed like an impossible thing to overcome, and in a way it was. The Demon Mark, that is, plus the situation with Star (her best friend and a former Fire Warden), Lewis, David and all the Wardens trying to catch and/or kill her. So the way it worked out was climactic, suspenseful and pleasing.
I don't actually have any negatives. Probably if I read other people's reviews or talked with people about this book, things would occur to me or I'd find myself agreeing with other people's criticisms, but I finished the book five minutes ago and am just coasting on the glowing aftermath of a finely written, entertaining, original story. As far as urban fantasy goes, this is a great addition to the genre. Loved it.
