When Marina Baker decided it was time to write a book she cast a spell to make it happen. Days later she was asked to write Spells for Teenage Witches. Better known in recent years as an environmental activist, she is the daughter of a white witch and used witchcraft for good all her life. She is delighted to have been given this opportunity to share her knowledge. "Sometimes it's pants being a teenager," she says. "I hope this book helps." She lives in a well insulated house with solar panels in Lewes, East Sussex. She has two teenage children.
