Recommend a read.....

[JennyorAlice]

As always, you can never have too much to read (at least, that's what I keep telling everyone). So I've been searching for some new manga to read and I've come across the following called Vegabond. Has anyone read it? Is there any other manga that you can suggest for me?

Synopsis:

 

[Nel]

is it really a manga? or a lightnovel?
is it long or short?
how would you rate it?
