Tiny is a little girl who lives on the shores of a mysterious lake. She watches the water as it laps on the shore and feels a deep desire to explore it but she knows that first she must prepare. She starts to take swiming lessons and she immerses herselves in books and tv shows which will help her achieve her goal.

Finally the day comes when she feels she is ready to jump in. She packs up the things she will need and heads to her chosen spot. She tests the water with her toe and checks that it is deep enough for her to jump in to and then she carefully climbs a tree whose long branches lean out over the lake.

She has thought about this moment for so long – but suddenly Tiny is filled with doubt. What if she can’t do it? What if something scary lives beneath the surface? What if? What if?
