My DD is enjoying learning to draw manga.  I was thinking about getting some manga books for her.  My concern is that I know that some of them can be non-chid friendly.  Others are fine.  DD is an Aspie who is not on the sophisticated side so I don't want anything that contains anything suggestive. 

can you suggest a series or book that might be appropriate?

Thanks for your help!

Whats an Aspie? XD

Hmm.. I think the first whole series I read when I was about 14 was Peach Girl.  Here's a link to the first book: http://www.tokyopop.com/product/1319/PeachGirlAuthentic/1

I dont remember there being anything too bad in it.

Fruits Basket http://www.tokyopop.com/product/1194/FruitsBasket/1 is a well known and popular series.

Also maybe try Imadoki http://www.viz.com/products/products.php?series_id=81 or Full Moon o Sagashite http://www.viz.com/products/products.php?series_id=342

Mermaid Melody, Gakuen Alice, and Card Captor Sakura are good.

Are there any particular genres she likes?

One series I'm always recommending to pretty much everyone I know is Yotsuba&!, a really charming all-ages comedy about the daily life of a somewhat eccentric little girl and the various adventures she gets into. Although I imagine not all 14-year-olds would be interested in reading a series with a child protagonist, so that's probably something to keep in mind (but then, I'm in my 20s and find the series hilarious, so who knows). Azumanga Daioh is another series by the same author, about a group of high-school girls, which is also very funny.

Or for something in completely different vein, Nausicaa of the Valley of the Wind, by Hayao Miyazaki (better known as a filmmaker), is a complex and serious fantasy-adventure epic (with beautiful artwork) that also gets my highest recommendation.

I would recommend Sailor Moon, Peach Girl, Card Captor Sakura, Peach Fuzz, Kare Kano, and Wish.

All of those are age appropriate IMO with very little or no sexual content.

Well I like Zodiac P.I. it is really good and it is short only 4 volumes.
