I'm searching for something like this but frankly there's nothing as far as I know. The best so far is Chinese Breeze series - example book
http://www.amazon.com/Whom-Chinese-Breeze-300-word-Level/dp/...
with stories a little, little better than usual. They, though, require that you know at least ~100 basic hanzis to be able to comfortably read. I have 3 or 4 books, I don't remember, and they are fine (just please, a little better story!) Each is around 20-40 pages so not much but kindle versions are also really cheap.
The way I worked with it, was to convert mobi to html and put on local server. That way I could use Zhongwen (mentioned by alexgolive) plugin to help me with words I didn't know.
If anyone knows something similar, please share! I love to read Hanzi, it's super fun when all the spiders :) suddenly start making sense
