I bought volumes 1-5 for my 8 and 10 year old daughters. The couldn't put the books down! The two of them made it through all 5 volumes and then re-read them! My older 11 and 13 year old daughters enjoyed the comics as well. We've pre-ordered vol 6.

We then bought the Joan of Arc comic and the girls tore through that as well.

Thank you, thank you, thank you. Fills a void for kids reading and my girls really enjoyed it.

My comments to the creators:
First off, I've read quite a few manga and comics, so I come at this with a tough eye. The artwork was good, relatively realistic for character design, which was nice. What most impressed me was that everything was colored (normal for American comics maybe but quite uncommon in the Asian industry where output demand is too high to permit time for coloring). Funny, there wasn't always consistency with where background people were standing from frame to frame. lol
The paneling was unexciting. Too many boxes. It's nicer when activity in panels overlaps at times and/or uses non-rectangles (like trapezoids) to appease the eyes, though admittedly it's not as convenient to color these. For example, you really missed out on making the tidal wave (that wrecked the boat) big and exciting; and that's all in the paneling.
The story felt a tad rushed, so the dialogue was speedy. Spoiler alert: The only deep character development we really got was to see Finnian was whiny, which doesn't make him a hero we want to follow.
I understand giving a background explanation in the introduction, but it would have been more intriguing to expose the details gradually through the story itself. Also, the topic of a fighting vikings might be more intriguing if you showed the actual evil doings of the vikings right off the bat so we have excitement and an enemy to hate, but that might be tough to swallow for a Catholic comic. Fighting can be dirty business though, and you picked the topic.
My advice is check out some popular Japanese manga since the Japanese are masters at it. There's a reason they're #1 in the world.
Overall all though, my applause for effort. Thanks for making wholesome comics for us believers.

My son tells me the two little boys (8 and 6) love the stories of Finnian and best of all - Joan of Arc. Seems the six year old playing in the yard called out "I am Joan of Arc" which of course caused the parental units to really chuckle. He had his "sword" ready to be put to work. Seems they read them every day and some days several times. Thank you!

My 10 year old son loves this comic book and asked for more.

Really enjoyed it and particularly the hard copy. I had viewed and read the series digitally but holding the printed version, which is beautiful gave it more power. I also like the authors comments inviting us into his process and derivative sources. Bravo!! Keep up the good work. Encore, encore!!!! Joe D’Alessandro, Wilmington, NC
