Gemma had a hard time figuring out what she wanted to be when she grew up. She worked as a film and television actress, a teddy bear importer, a department store administrator, a preschool teacher, a temporary tattoo artist, and a 900 number psychic, before finally selling her first book, Spying in High Heels, in 2005 and deciding to be a writer.
Since then, Gemma has written several mystery novels and been the recipient of numerous awards, including a National Reader's Choice award and three RITA nominations.
Gemma now makes her home in the San Francisco Bay area where she is hard at work on her next book.
