One day, Emily gets a balloon. By the end of the afternoon, the balloon is no longer just a plaything—Emily and the balloon are friends. But when the balloon blows away, what will Emily do? Sweet, compelling, and filled with beautifully evocative illustrations, the timeless innocence of a story about the wonder and discovery of friendship makes this deceptively simple book a classic.
