Izzy and her friend Frank spend blue-sky-sunny days and grey-cloud-rainy days roaming and playing by the sea. But when Izzy has to leave her lighthouse and island life behind to move to the city, she also has to say goodbye to Frank. The city is crowded and noisy, and Izzy misses the sane and the sea. Can Izzy find a place for herself in her new home? And will she ever see Frank again?
