Well, I finally decided to continue this series, and to my surprise it's already completely scanlated:

This was quite a good series, though it wasn't as strong in the final couple of volumes. Decent ending, though it felt quite rushed and I would've liked a bit more of character interaction when things concluded. Seems like there's more to be said.

Any of you read it all?
