"When Grandmother Ate my Cat" is Henna's first book. Henna is from Finland and the book recounts an episode from her childhood when her own grandmother really did eat her cat! The book has recently taken on a new significance when Henna became a new mum - "Its a wonderful opportunity to pass on something magical from my life to my son". Henna trained as an artist working mainly with video and installation. Her work is mainly concerned with the natural world and she has worked alongside other artists, scientists and environmentalists on a wide range of projects.
