Heroes of all shapes and sizesNon-fiction and historical fictionKids' graphic novel favorites
Second: I have it posted a visual flow chart of suggested summer reading for young adults middle-school and older. While the info-graphic covers classic of all sorts, my list focuses on graphic novels, demonstrating that there is quality reading to be had by kids of ALL AGES, and ALL TASTES.
