Over The Wall - Peter Wartman
This was such a fun read! Very quick, too--very, very quick. I think I finished it within 15 minutes.

The story follows a young girl venturing inside an abandoned, walled-off city to find her brother, whom she can't quite remember. In this city she finds a demon who becomes her very sarcastic guide, and she unravels the mystery of the city and the one behind what's keeping her brother trapped inside.

I lovethe art style. That and the color palette of black, purple, and white led me to pick up this novel in the first place. It's bold and expressive, perfect for younger readers.

I wished it had been a little longer, to expand upon the mythology of its world and its history, but as it is it's definitely not a bad read.
