Even if your little sprouts seem to set up a grudge match over just about everything: choosing the Friday night movie, toppled LEGO towers, and endless hours of she-touched-me-again, in the end, a brother or sister is a built-in best friend. (Who better to help drive Mom crazy or snicker with at Dad’s creative cooking?). Flip through the album to see our picks for best picture and chapter books celebrating the ultimate family bond.

The Penderwicks: A Summer Tale of Four Sisters, Two Rabbits, and a Very Interesting Boy

Age: 7-11

This first in a popular series (and winner of the 2005 National Book Award) features four very different sisters on summer vacation in the Berkshires. Like a modern-day Little Women, the chapters alternate among the girls’ points-of-view as they make friends with a neighboring boy and fall into one adventure after another. Pick this up as a fantastic read-aloud for school-aged kids.

Available at amazon.com, $7.19.
