When sister and brother, Susi and Bobby, are outside playing one day, they discover a yellow butterfly that sings.  They are so amazed that they share their experience with their grandfather at dinner, who in turn shares a legend that says that yellow butterflies are magical and can grant wishes, if those wishes come from the heart.  Bobby and Susi immediately start plotting and planning what they’d like to wish for, and spend days trying to catch the butterfly.  When they finally catch it in their net, they start spouting their wishes, but get no response and notice that the butterfly is in distress.  Unable to convince her brother to set the butterfly free, Susi wishes the butterfly free, and so it happens.  In gratitude, the free butterfly decides to grant them both a wish, and the story ends there, asking the reader, “What would you wish for?”  It reads aloud well, and would make a great conversation starter, as so many kids love to ponder the ending question, and it has a good message to offer about unselfish actions getting rewarded in the end, but that message is a bit muddled in that Bobby gets granted a wish, too, even though he was the one arguing to keep the butterfly captive.
