This book is not for everyone. It is extremely scary and disturbing. At the same time, it is a fascinating look at the police work and prosecution that brought the murderous Manson Family to justice. The book is hard to put down; the in depth discussion on presenting a criminal case in court and developing evidence to support the case is outstanding. The main complaint is that the book is a few hundred pages too long. The author seems a little too self-promoting, but then again he did get a prosecution on one of the biggest murders in history.

This is the WORST CD-ROM game I have ever seen! My 7-year-old daughter longed for this game all Christmas season and she is bored out of her mind with it after one hour. It is slow, skippy, etc. running on a new computer! Don't waste your money like we did, skip right over this dud.

I initially bought the movie just because Stephen Colletti (who I'm in love with) was one of the leads...and I really didn't expect much from what looks to be a low-budget indie horror flick. But, I really did like it! The lead girl who plays Jennifer (Nikki DeLoach) is really good. I can't believe I've never seen her in anything before? Maybe I have, but I didn't know!?! It was cool to see the guy from Weekend at Bernie's (Terry Kiser)...he is a really good actor. Too bad he was dead the whole time in both movies I saw him in, lol. Anyways, this was a cool movie and I'm glad I got it!
