Researching her school project on Fairtrade has been a real eye-opener for Maya. She loves clothes and is appalled to find that her favourite sparkly T-shirts are made by poor children in other countries who lead very different lives from her own, privileged one. She knows she must do something about it, but how can she make a difference without revealing her pop star secret to the world? A brilliant series about four friends who know you’re never to small to make a big impact! From bestselling author Holly Webb. With cover illustration by Owen Gildersleeve.
