Buying gifts for "tweens" (those young, middle-school-aged people who aren't quite teens, but are more mature than kids in grade school) can put the gift giver in a pickle. Their reading abilities are probably fairly solid and they are likely interested in young adult books that have made their way into pop culture, like the ubiquitous Hunger Games books. You don't want to offend them by selecting titles that are "for little kids," but you also don't want to upset any parents who might find a book's subject matter too mature for their tween.
