Three girls - Grace, Jada, and Malia - all facing worries and loneliness and all brought together by a mysterious box and a kind librarian. All 3 girls take turns "checking out" a locked box and leaving treasures in it. What they don't realize is that these treasures are bringing hope to the others when they are found and are drawing the three into a magical friendship. This was a sweet story. At times it was hard to remember who was who, especially when some of their stories overlapped. The ending was very satisfying though.
