I think Millenium is better, because it is real. It can really happen. You can imagine it. You can't really imagine witches killing babies... But I think War of the Witches is a better book for young people. Millenium is too much blood and sex inside for children. It's also harder to read than War of the Witches. I don't say War of the Witches is bad. It's very well written. I like them, but I only say I prefer Millenium. But maybe I am too old to read War of the Witches... I understand people disagree with me, but don't be angry!!! It's an opinion.
