'Emiline: Knight in Training' (Oni Press), by Kimberli Johnson, is a charming story for younger children about a group of knights who are on a quest, one that includes learning to read. The twist is that the book is tailored for children with dyslexia: The font is dyslexia-friendly, and the art, in charming low-key pastels, is low-contrast as well. (Ages 6-10, $12.99)
