I have seen some kids at my school reading manga (I think that's what its called) and I have also seen some in my local library. I think it looks really interesting and I'd love to give it a try- I just don't know where to start. In my library it all seems to be in a totally random order like they have volumes 6, 19, and 14 for a random series,and they don't have the first one of any series. I have also looked it up on the internet and there is just so much I don't know where to start!
I'd be very happy if someone could give me some tips on how to get into manga and if they could recommend some to me- I really like animals and cats if that helps :)

Just buy your first complete one. After that you can checkout from library or whatever.

But your first BOUGHT one should be a great experience.
I'm not into it myself but some people are

Perhaps ask the other kids to see if you can read theirs?
