When her mum ends up in a coma after having a new baby, Ella is left coping with her well-meaning but shambolic stepdad – and a tiny newborn brother. Her main distraction from all her worries is her school project about whales. Ella is fascinated by the idea of whale song, when they call out to each other to attract a mate. The amazing story of one whale who sang non-stop for twenty-two hours gives her an idea. Could the whale song reach Mum and show her how much Ella cares? Would this help bring Mum back to Ella and new baby Samson?

This is a tender, moving story – classic Jacqueline Wilson.
