"Expect great lack of originality in Nightshade City." I'm not sure how much Mr. Riordan actually supports the endorsement made on the cover of the book, but it's not exactly accurate.
Now don't get me wrong. This book was ok. It's not like it's washed up trash or anything, or even that it's bad. It's that it's just ok. And that's the problem.
First of all, nothing that happened in this book was unpredictable at all. You can call the ending from the first few pages, and since there's legitimately NO twists or anything of that sort in this story, you would be at least ninety percent right. This book was boring, not because there wasn't action, or characters, but because you knew the ending from the first 10 pages. I was half afraid half excited to get to the end of this book, excited because I imagined a whole lot of things the author could do to twist the story and make it meaningful and an interesting piece of literature, afraid, because from what I'd seen so far, in that all of my predictions had been made to be correct, had gone off without a hitch. There was nothing in this book that surprised me, even slightly. Mrs. Wagner does a good job of making you think she's going to twist the ending and then she goes and laughs in your face and it's the exact ending you were expecting.
Not getting into spoilers (although, there aren't any, really, because nothing happens you don't know will happen), but the basic set-up is this: there was this peaceful city of rats. Big rat and his evil henchmen overthrow the peaceful city and set up a dictatorship. Good rats set up rebellion to overthrow dictator. Does that sound like Star Wars to you? Yeah, sounds exactly like it to me too. There is no originality in this book. Everything you know will happen happens. There are no stakes because from what you see in the first hundred pages it's obvious the ending will be a happy one, where literally no one dies.
Unfortunately the fact that Mrs. Wagner set herself up for a sequel worries me. She's not a terrible writer. As I said she's just ok. She should move on from this plot line (one that's been used countless times, except this one has rats and no light sabers or ewoks) and try to practice her craft and make something unique. Something not like this. Her actions scenes have ok detail, and for the most part they're not boring, even though you know what will happen. Her dialogue is hot garbage, and her character work is seriously lacking. The Catacombs (city ruled by dictator) lies underneath a modernized city: TVs, gardens, traps, etc. So the fact that all of the characters here speak like they're in a bad Shakespearean play is troublesome. At one point a character yells at big bad guy "my ill will towards you knows no bounds!" Unless Mrs. Wagner is living under a bridge, people don't talk like this anymore. And you could defend it, sure. You could say the rats aren't as advanced as a humans, which is true. But when Mrs. Wagner lets the humans talk, a human CHILD no less, and he sounds exactly like Shakespeare, I see a couple of problems with that. The dialogue is plastic and the characters either defined by one personality trait or none at all. Big bad is a bad guy. Henchmen is mean. Big good is good guy. Male protagonist is brave. Female protagonist is scared. K.
Again, this is an ok book. For fans of Redwall and those who are looking for a comfort story with no themes or deeper thought, or anything that involves stakes, this is a good read. Wagner's writing isn't atrocious, save the dialogue. If you have a kid it doesn't hurt at all to read it to them. Again it's not a bad book. It's not good either, or special. But it's not bad. Additionally, this was written by a first-time author, and Wagner can be forgiven for a large number of the mistakes she made in the crafting of this book. I'd look forward to any future work. For now, though, while a good first attempt, this book was unoriginal, with extremely formal dialogue which is painful to read at times, with no twists or turns whatsoever.
