Claire Craig (whose pen-name is Petra James) wanted to be an archaeologist when she grew up. Instead, she became a book editor. After writing several non-fiction titles for children, and some fiction readers for non-native speakers of English, she began writing stories about a nine-year-old girl who wanted to be a poet when she grew up. Claire is currently the Children's Publisher at Pan Macmillan. Claire also publishes under the name of Petra James and is the author of the Harriet Bright series and the successful Arkie Sparkle series.
