A touching picture book about love, bravery, and learning to swim. Where waves crash and smash and all creatures swim wild, an otter gave birth to a sea otter child. There's nothing Lottie the otter loves more than swimming hand-in-hand with her Mum. Sometimes she wishes she could join her friends as they play under the waves, but she's not sure she's brave enough to join them. When a big wave comes and separates her from her mum, can Lottie find her brave and swim down to save her?
