Query: Heart of a Jaguar review by a Rapine expert

The book heart of a Jaguar is really weird. It's about a boy named Balam; he lives in a villiage near Chichen Itza. There was a terriable drought. The people in Balam's villiage has to please the god with sacrifices inorder to get rain.It has a lot of violence thorough out the book.
