It's been four years since the Dark Days when Chloe lost her mum to cancer. Nana’s been wonderful but it’s time their family had a mum person. When Dad brings home a special friend Chloe knows immediately that Fern is wrong for the job. She’s in a wheelchair so can’t skate to the shop, turn cartwheels on the lawn or race along the seashore. Chloe will have to be good at being bad to stop Fern joining their family. Or is she making a mistake? What if Fern is the perfect mum for the job? A warm-hearted story about letting go of limiting expectations and opening up to 'can' rather than 'can't.'
