This is a tender and gentle story that will captivate readers of 8+ from bestselling author Jacqueline Wilson.

Ella's mum's in a deep coma having just had a new baby.

That means Ella has to live with Jack, her hopeless stepfather and cope with her tiny newborn brother, as well as worrying about Mum.

The only thing that's going right is her school project.

It's all about whales and how they sing out to each other to attract a mate - sometimes for hours.

Maybe a whale song could reach Mum, wherever she is, and bring her back to Ella and baby Samson.

Surely it's worth a try?
