"A moving tale of love, fear, and the courage of letting go. Beyond the hill where the tree lives, lies Who Knows Where. Every year when the wind blows, the tree's seeds sail to this mysterious place--until the day an especially tiny seed decides to remain on its branch. At first, the tree feels the seed should leave. If it doesn't, it will never grow roots of its own. But the tree also feels lonely, and Who Knows Where is...who knows? This strikingly illustrated picture book celebrates the rhythms of the natural world as it gently reminds parents and children that letting go and being brave can lead to life's greatest adventures.".
