Example Input: I really, really love Cliff Janeways' books. The ultimate in smart mysteries.... . Janeway has opened an entire new world to me. As an avid reader who has a book in almost every room in the house including the garage, bathroom, and who reads during ironing, doing homework, or waiting for sugar to boil for making English Toffee, I can almost assuredly recognize not only genres but also the various nuances within the genres. JUst as women in this day and age tend to head towards tough broads who can fend for themselves in a man's world, Janeway brings in a cop whose adoration of written materal causes him to leave his probably more steady job as a policemen, to enter the world of rare books. An occasional job will bring in enough money to support his chosen lifestyle for a while, but more than that, his introduction into the interesting and secretive world of bibliophiles. These books not only whet my appetite for this world, but also introduces me to both real people and real books that helped to shape our world from behind the scenes.     Janeway's current flame has an old friend (who also delved into books) killed, and she wants him to find out who did it an what t he motive was. In doing so he ends up becoming involved in his lover's old friends and flames, so of which should be left undisturbed. But Janeway never  is one to back down from a fight over 'rights and wrongs', and he doesnt' do that in this book either. I get the feeling when I read other reviews that the readers want something less complicated than what Janeway provides. If uncomplicated is what the readers want then they should go to other books, becasue there are times in Janeway's books that you just have to go back and understand why certain things are said or done in a true historical background and reality.     I wish Janeway could write fast than he does, because I thoroughly enjoy these very educated mysteries, but then, if he did write that way Janeway would not be as enjoyable as he is.    Karen L.

Example Input: From the Same Minds That Brought You Joel Osteen . I purchased Eldredge's "Wild at Heart", and I didn't think it was scripturally sound. I was given "Waking the Dead" as a present, so I tried to read it as well. I finally gave it up.     John Eldredge's writing is typical of today's movement to bring the world into the church. Trying to show a young Christian the religious aspects of movies like "The Matrix" may work, but to my 48 year old ears it rings very hollow. Perhaps it boils down to how much you will dilute Christ's message to get people to listen. For better or worse, I have little patience for it.     The author also presents the image of God as "my friend". To me this is nothing but another watering down of the Gospel message to get the world to accept it. Giving the Creator human attributes brings Him down to a level where we can work things out between us. I can't find that kind of relationship in any legitimate Bible translation. After all, my friend wouldn't let my saintly mother die, and save a worthless drug addict now would he? God my friend probably wouldn't have sent His Son to die for my worthless self anyway.     This is exactly the same theology as building the largest "Christian" church in the United States, and not putting any crosses in it so as not to "offend anyone". It's the same as getting on a nationally televised program, and stuttering about whether you believe those who don't accept Christ are doomed to hell. When you profess to be a Christian minister or author and you can't speak correctly of what Christianity teaches, it's time to examine just what you really believe. God's word is not always easy to swallow. Either it's the truth or it isn't.     Mr. Eldredge also speaks often of "setting hearts free". While I do believe hearts are free when released from sin, a Christian is bought and paid for with Christ's blood and not "free" at all. Titus 1 (KJ) begins, "Paul, a servant of God,and an apostle of Jesus Christ"...Christians ARE freed, but to begin a life of service.     For a more accurate and fulfilling study, I recommend "The Way of the Master" books and videos by Ray Comfort/Kirk Cameron.
