Kings ended up being the last of this series, although there are many indications that a fifth book was planned....no evidence that it ever was written.
Kings does a good job of taking the reader to the attempted murder of the man who would be known as the "Anti-Christ". The principal characters and their roles in the story are clear, those who are meant to meet - do, those who are meant to come to believe in the words as given in the Christian Bible - do.
Unfortunately for the reader, we are left hanging with a lot of loose ends. We end with the "revival" of the Anti-Christ and his destruction of the Temple Mount in Jerusalem.
This may have been a good place to leave the reader....at least those of us who are familiar with the real Biblical storyline.
Despite being left with all sorts of questions about where the authors intended to take the series, I still can reccomend the 4 books as an interesting read and will say that unlike a few other reviews of this series, I am pleased that I discovered the books and pleased with the entertainment and provocative questions the books provided me.
