Beautiful city of the dead

The first time I read this book was back in 2008. I was in 8th grade. I hated reading because every book that I ever picked up was not my style/cup of tea. Then one day I saw this little book on my teacher's bookshelf and asked if I could read it. That day was the day I fell in love with reading. This book is unique with a little hint of W.I.T.C.H. elements in there. Ever since 2008, I have been looking for similar books like this. Yet, I have not found any.

I just finished rereading it in 2023, over a decade later. One of the oldest books on my shelf.
