Louise Arnold was born in Morden, Surrey. Her love of writing began at the age of four when she wrote her first poem. From the age of eight she lived in Bognor Regis until passing her A-Levels. Louise took a year out before university and back-packed, Amtrak'ed and GreyHound-ed across America. She graduated in 2003, from the University of Kent, with a 2. 1 in drama (specialising in Stand-Up Comedy) and has now settled in Canterbury with her partner. Her spare time is taken up with a love of e-bay and carboot sales, changing the colour of her hair, and borrowing the neighbour's cat until she can buy her own Siamese. Grey Arthur: The Invisible Friend is her first novel.
