I doubt you will find anything more advanced than kindegarten level or basic textbooks that use pinyin. If you want to start reading more mature material at a high level in Chinese, you are going to have to learn to read Hanzi!

Chinese is not written using pinyin! It is there purely as a guide to teach pronunciation and to help very young Chinese children as they start to learn to read but don't know enough hanzi and to help foreigners learn prounciation. 

@kraut: i totally understand your concern that learning by pinyin is dangerous and  a bad habit. however, i am a german born chinese. thanks to my parents i am able to speak fluent chinese 100% accent-free with a vocaulary easily exceeding 1000 characters. i know it sounds weird but i just cannot read/write. (i just never had to use it). with that, i can skip the process of learning new words, grammar, pronunciation etc. and just focus on learning those characters...and for that, i think this method would totally suit my situation. knowing pinyin is also necessary for typing chinese on pc :)

big thanks to all the suggestions, this was a big help for me
