Reddit reviews Fredrik Fompel og Tankemonstrene (Norwegian Edition)

I am about halfway through the Duolingo course right now, which I LOVE. It is so well designed and I am seeing huge improvements already and can recall a lot of what I've learned. I am supplementing with "Norsk, nordmenn og Norge", which I haven't used too much yet, but I am enjoying as well. What are some good children/teen novels that I could start to read after I finish my beginning courses? I do not mind having to translate some since it will strengthen my vocab and hopefully I'll be able to recall okay by the end of the book. I want something more advance than a kid's little book, more of a young reader's novel. Any suggestions? I have this book on my list but would love help finding others (unfortunately Amazon doesn't have too many options): http://www.amazon.com/dp/8299968003/ref=wl_it_dp_o_pC_nS_ttl?_encoding=UTF8&colid=242RS6W9R88E9&coliid=I1AT5LPZWLYCDP
