Odd book about a girl named Alexa in a city entirely walled off from a forest down to the roads coming in and going out. The convicts who built the city and are abandoned outside are falling under the sway of a person named Sebastian, and plan to invade. It's up to Alexa and some talking animals to stop them.
There's just too many odd decisions and twists to make sense. They mentioned building the walls to stave off some evil, but what evil and why are the convicts immune to it? Why does Alexa need talking animals to stave off what is a rather mundane threat? Why does Elyon matter, or the fact that talking animals are finding it harder to talk? The world didn't really feel cohesive to me, but disjointed and with background information sadly missing. The author mentions that he told this first as a serial story to his daughters, and I think it shows.
It also ends rather abruptly, especially for a serial story as part of a trilogy. Without spoilers, you get the sense he thought there might only be one book, and rather than let it continue on, he felt he needed to resolve one of the important parts a bit too quickly.
The writing isn't too bad, but the odd disjointed plot might throw you off. I can't really recommend it.
