Amazon affiliate -- Adsense won't accept my site

Hi Folks,

I'm trying to get a website up and running. The target market is people who are 50+. Basically it offers some original content and links to a book on Amazon with more info. I applied for adsense and got turned down. They said my site had copyright material on it.

I suppose in a way it does. I usually give my subscribers a notice of when a book that they might be interested in is free. I download the book, review it, and then typically I will copy the image out of the Kindle book and make it look a little nicer. Of course I hope that people who come along after it isn't free, will click on the link and buy it for the $2-$3... or whatever....

I'd like to show you an example post, it that's OK here:
Over Fifty at Risk for Shingles | 50alone.com

From this post, you will see in one paragraph I quote the author, which was in the description on the Amazon page. It says:

Ryan Notch has written a guide, Shingles -- A Quick Guide to Symptoms, Treatment and Pain Relief. He says, "Doctors now estimate that 50% of us who live to the age of 85 will catch it at some point. What was once only a disease for the elderly is now attacking all portions of the population. Especially those whose immune systems are compromised by stress or age. This book is the simplest and most comprehensive guide to recognizing the signs of shingles, and ways to deal with both the short term and long term pain. Presented in terms direct enough for the common reader, but smart enough to get you the information you need to beat this disease for good."

You note, I've given the author credit for what he says.

So my site is sitting at a PR of 1, and Adsense won't accept me into their program because of copyright infringement --and I'm guessing the same issue will prevent my site from getting a better PR in the next Goggle update.

So what do I do? Stop making the book images look better? Stop quoting the author? Or should I just give up ~~~~~.

If you can offer some suggestion and help, I would sure appreciate it.

Thanks,
Steve MacLellan
