I'd not heard of it until last week, when folks on r/books were singing its praises in a thread, so figured I'd give it a shot. Yeah, it's enjoyable. Definitely aimed squarely at the middle of the YA crowd, but it's an easy read at a time when my brain isn't letting me really get into any books.
Barker has a fascinating imagination. I finished Coldheart canyon recently. I almost walked away repulsed many times but there was good story under all his signature flair. After Imajica I will try to read anything he writes.
