More like a 3, but I really liked the charm of this story and the focus on the need for community.  There's also the subtle message that your family doesn't have to be who you were born to but the ones who loved and took care of you instead.

The different creatures of the world were fun! There's a mixture of imaginative and realistic creatures. The artwork is simple but extremely effective in conveying the story. The scenes in the cave were a pleasure to look at.

I hope this could become a series.
