Pip Jones lives in East London with her partner, her two daughters and a real invisible cat (it doesn't catch mice, but it doesn't need a litter tray either, so there are pros and cons).

She writes a lot. She even owns a writing cloak! And she spends days on end working out how to get good rhymes, such as 'snuffle' and 'kerfuffle', into stories. Pip won the inaugural Greenhouse Funny Prize in 2012 with Squishy McFluff, The Invisible Cat, her first book.
