With the type of closures and the amount of compression it is meant to give it's really difficult to put on. You need a hand to pull it closed in order to actually be able to close each of the 20 some odd hooks.

Koontz can write. But he sucks as a story teller. Books are supposed to have a COMPLETE story in them, no? Well this one has no ending. No end at all. These 2 detectives are clued in to the fact that Dr Frankenstein exists, and is creating his "perfect race" to some day kill off all humans. That's it. You meet the original, now educated and "at one with the universe" Frankenstein's monster, you meet the main characters, and they have some conflict. That's the whole "story" in this book, which it really isn't because the basic elements of a story are a beginning, middle, and end.

Ex Output:
Negative

I fell in love with Brasilian jazz my first trip to Rio. I've been there many times and was always amazed, visiting the little clubs, listening to a lot of great players. I don't remember how I found this guy, but, understanding music 'from the heart', Leo understands, and plays it that way. In my view, he is one of the most sensitive sax players I've ever heard - check out #3 on Black Pearls, you'll see what I mean..... I think it would be a great project for Leo to hook up with Bob James and Fourplay, and let Leo play, I mean feature him, write and produce songs that bring out his talent, give him lots of freedom. I rated this 4 stars, simply because of a couple of songs I skip pver, but all in all, it's great listening. And as a bassplayer, I've spent hours playing along with him.
