"With the Light"

So, I was browsing my local Borders bookstore (it's closing ) last night. I was checking out the manga, and I came across a series that piqued my curiosity. It's called With the Light and it's about a mother and her autistic son. I thought it was a rather unique concept for a manga. Still, I didn't buy it because I don't know how good it is.

Has anyone read it? Is it any good? How many volumes are there (I saw volumes 1 through 7 at the store) and will there be more volumes to come?
