Books are a portal to our personal histories. Pick up a worn copy of a childhood favorite and you might be transported to the warmth of a parent's arms or a beanbag chair in a first-grade classroom or a library in your hometown.
Avid readers could build autobiographies around their favorite books and come to the realization that what they have read is almost as meaningful as when they read it. A high schooler poring over "To Kill a Mockingbird" for a summer reading assignment encounters a different book than someone who reads it decades later, closer in age and outlook to Atticus than Scout.
In light of that reality, we took a stab at picking the best book for every age. There's no definitive way to do this, of course. What moves one reader may not resonate with another, regardless of their birth year. So think of this list as a starting point, plus an invitation to look back at your own literary chronology: What spoke to you during a certain time in your life - and why?
Here are our picks for worthwhile books to read during each year of life, from 1 to 100, along with some of the age-appropriate wisdom they impart. — Stephanie Merry, Book World editor
