Grey Arthur is a ghost who hasn't found his place in the world. Tom Golden is a boy who doesn't fit in at school. When Tom and Grey Arthur mutter the same three words, "Life isn't fair," at exactly the same moment, a connection is made between them. Suddenly Grey Arthur knows what he must do: He must become Tom's Invisible Friend.

It seems like such a brilliant idea! Grey Arthur can take teasing signs off Tom's back, make sure he has a pen in class, keep the bullies at bay, and generally take care of everything a best friend would do. He feels a great satisfaction in helping his new friend (despite the fact that Tom doesn't even know he exists), but then everything changes when an accident gives Tom the ability to see Grey Arthur and the rest of the ghost world. Now everyone wants a piece of Tom! Poltergeists, Faintly Reals, Sadness Summoners, Snorgles, Chain Rattlers...they're all lined up for their moment with the famous Tom Golden. Add two confused parents, a kidnapping, and a few embarrassing moments at school, and soon Tom and Grey Arthur are pushed to their limit, leading them to discover what true friendship is all about.

Louise Arnold's fantastic, funny, heartwarming debut novel will have readers laughing out loud and cheering as Grey Arthur and Tom, outcasts in their separate worlds, join forces to turn their luck around.
