If you’re looking for recommendations for a younger person, take a look at the American Library Association’s 2021 list of notable books. These titles have been considered by their committee of professionals:
“Each year a committee of the Association for Library Service to Children (ALSC) identifies the best of the best in children’s books. According to the Notables Criteria, “notable” is defined as: Worthy of note or notice, important, distinguished, outstanding. As applied to children’s books, notable should be thought to include books of especially commendable quality, books that exhibit venturesome creativity, and books of fiction, information, poetry and pictures for all age levels (birth through age 14) that reflect and encourage children’s interests in exemplary ways.”
The list contains titles for preschoolers up to age 14 as well as an ‘All Ages’ category.
