I loved this graphic novel and it was a big hit with our 4th & 5th graders.
As far as how often to post, I think it is an individual decision. I try to post reviews as I finish reading, but I am currently 3 or 4 books behind. I noticed a lot of people post reviews as they finish books and then have an end of the month recap post.
I was posting right after finishing but that meant my followers had no consistency for when to check the blog. I started doing once a week on Fridays and for a while added Tuesdays as well. The problem is I now have a backlog of reviews to write and I want to finish up before the end of the year to start fresh.
